A Scale to Measure the Perception of Graduates towards Student READY Programme

A scale was developed to measure the perception of graduates towards Student READY Programme (SRP). The Likert’s summated rating scale was followed in the construction of scale. Based on the review of literature and discussion with the expert’s, 49 statements were enlisted. The relevancy rating were sent to 160 scientists and extension specialists working in research institutes of Indian Council of Agricultural Research (ICAR) and State Agricultural University (SAU) for critical evaluation of statements on a 5 point continuum. Out of 160 judges 66 responded within a period of one month. Based on their judgment 40 statements were isolated in the first stage of screening by finding the relevancy weightage scores. Statements having relevancy weightage of more than 0.70, relevancy percentage of more than 70 per cent and mean relevancy score of more than 3.70 were considered for final selection. By this process, 32 statements were isolated in the first stage of screening, which were suitably modified and rewritten wherever applicable. Eight statements were added as per the comments of experts. Thus finally 40 statements were selected for item analysis. In item analysis the selected statements were administered to 80 agriculture graduates of non-sample area of Tamil Nadu and Karnataka. Finally a total of 28 statements were selected for the study based on ‘t’ values (> 1.75) resulted from the item analysis and were included in the final scale. The ‘r’ value of the scale was found to be 0.922, which was highly significant at one per cent level indicating the high reliability of the scale. Hence, the scale developed was found to be reliable and valid. The instrument developed to measure the perception of graduates towards Student READY Programme (SRP) can be used by the researchers.

Assessment of Insecticide Resistance in Spodoptera litura (Fabricius) in Vegetable Crop Ecosystem

One of the most prevalent insect pests is the tobacco caterpillar or Spodoptera litura (Fabricius), which results in significant crop losses developed resistance against different insecticides over time. This laboratory experiment was carried out in the Department of Entomology, College of Agriculture, Rajendranagar, Professor Jayashankar Telangana State Agricultural University (PJTSAU), Hyderabad during Karif, 2022. The susceptible population was reared in laboratory continuously for ten generation without exposing it to insecticides. The susceptibility of field populations of S. litura that were collected from many vegetable crops in the intense vegetable crop cultivating mandals i.e., Chevella and Maheshwaram of Rangareddy district to commonly used insecticides viz., chlorantraniliprole, emamectin benzoate and flubendamide was then compared with a laboratory reared susceptible population The bioassay studies revealed that the LC50 values of these insecticides were significantly higher in the field population collected from Chevella and Maheshwaram compared to the susceptible laboratory population. Based on the LC50 values the Resistant ratio (RR) was calculated for the field populations. It was found that Chevella population developed 35.34 folds resistance and Maheshwaram population also developed nearly 34.90-fold resistance against emamectin benzoate. Both Chevella and Maheshwaram populations were found to develop moderate resistance of 28.23 and 27.35-fold against flubendamide and comparatively lower resistance of 21.05 and 23.44-fold resistance against chlorantraniliprole when compared to susceptible population. These findings further helps in developing better IRM strategies.

A field experiment was conducted during rainy (kharif) season of 2019 at research farm of Professor Jayashankar Telangana State Agricultural University, Rajendranagar, Hyderabad, Telangana to study the effect of sowing dates and nitrogen levels on growth, yield and nutrient uptake of browntop millet [Brachiaria ramosa (L.) Stapf]. The experiment was laid out in a randomized block design (RBD) on sandy loam soil with factorial concept consisting of 4 dates of sowing (June 15th, June 30th, July 15th and July 30th) and 4 nitrogen levels (0, 20, 40 and 60 kg/ha) with 3 replications. Results showed that leaf area (683, 1530 and 1412 cm2 /plant), dry-matter production (248, 540, 622 g/m2 ), number of panicles/m2 (6.52), panicle length (17.82 cm), grains/panicle (147.92), grain (2,003 kg/ha) and straw yield (3,930 kg/ha); and nutrient uptake (N, P and K) at tillering, flowering and harvest (grain and straw) were significantly higher with June 15th sowing. Among N levels, application of 60 kg N/ha recorded highest leaf area (735, 1,560 and 1,437 cm2/plant), dry-matter production (243, 523 and 619 g/m2 ), number of panicles/m2 (6.48), panicle length (19.08 cm), grains/panicle (152.42), grain (1,921 kg/ha) and straw yield (3,949 kg/ha), and nutrient uptake (N, P and K) at tillering, flowering and harvest (grain and straw) but was at par with 40 kg N/ha over 20 and 0 kg N/ha.

Effect of Kharif Paddy Straw Management Options on Nitrogen Requirement to Rabi Paddy

A study conducted during the rabi season of 2020-21 at the Regional Agricultural Research Station, Polasa, Jagtial, under the auspices of Professor Jayashankar Telangana State Agricultural University, yielded insightful findings. The investigation revealed that incorporating paddy straw with a C:N ratio of 71:1 led to the immobilization of soil mineral nitrogen. Specifically, during 7, 15, and 30 days after treatment (DAT), approximately 7.2, 9.3, and 7.03 kg ha-1 of available nitrogen respectively was immobilized without phosphorus, whereas with phosphorus addition, the figures rose to 10.94, 14.75, and 11.04 kg ha-1 during the same time frames. Notably, after harvest of rabi rice significantly higher soil available nitrogen levels were recorded under paddy straw incorporation with phosphorus (169.7 kg ha-1), followed by incorporation without phosphorus (161.2 kg ha-1), and paddy straw burning (151.9 kg ha-1). Moreover, the application of nitrogen at graded levels impacted soil available nitrogen. Based on these findings, it was recommended, to counteract the immobilization effect and maximize crop yield, it was advised to apply 15% excess of recommended dose of nitrogen (RDN), as basal application.

Influence of cover crop residue and residual herbicide on emergence dynamics of glyphosate-resistant Palmer amaranth (Amaranthus palmeri) in grain sorghum

Abstract A field study was conducted from 2020 to 2023 at Kansas State University Agricultural Research Center near Hays, KS, to understand the emergence dynamics and periodicity of glyphosate-resistant (GR) Palmer amaranth (Amaranthus palmeri S. Watson) as influenced by cover crop (CC) residue and residual herbicide in grain sorghum [Sorghum bicolor (L.) Moench]. The study site was under a wheat (Triticum aestivum L.)–sorghum–fallow rotation with a natural seedbank of GR A. palmeri. Treatments included (1) fall-planted CC mixture [winter triticale (×Triticosecale Wittm. ex A. Camus [Secale × Triticum])/winter peas (Pisum sativum L.)/rapeseed (Brassica napus L.)/radish (Raphanus sativus L.)] after wheat harvest and terminated at triticale heading stage (next spring before sorghum planting) with glyphosate alone or (2) glyphosate plus acetochlor/atrazine, (3) chemical fallow (no CC but treated with acetochlor/atrazine and dicamba before sorghum planting), and (4) nontreated control (no CC and no herbicide). Results indicated that CC terminated with glyphosate plus acetochlor/atrazine had a delayed and reduced cumulative emergence of GR A. palmeri as compared with chemical fallow and CC terminated with glyphosate alone across all 3 yr. Compared with chemical fallow, the CC terminated with glyphosate alone and glyphosate plus acetochlor/atrazine required 66 to 643 and 105 to 1,257 more cumulative growing degree days, respectively, to achieve 90% cumulative emergence of GR A. palmeri across all 3 yr. The combined effect of CC residue with glyphosate plus acetochlor/atrazine reduced the total emergence counts of GR A. palmeri by 42% to 56% and 82% to 94% as compared with chemical fallow and nontreated control, respectively. These results suggest that fall-planted CC combined with a residual herbicide at termination can be utilized for GR A. palmeri suppression in grain sorghum.

Avifaunal Diversity in Telangana State: A Case Study in Campus of Professor Jayashankar Telangana State Agricultural University, Rajendranagar, Hyderabad, India

Population Studies on different agricultural and other bird species were carried out at Students farm, College farm, Agri biodiversity park, and Agricultural Research Institute farm areas of Professor Jayashankar Telangana State Agricultural University (PJTSAU) Campus in semiarid region of Telangana state covering an area of about 36 Sq.km. for a period of eleven years (2012 to 2023). Population diversity of 92 species of different birds, and their distribution within the university campus farm areas were recorded. Important among them are 9 species namely: Blue rock pigeon (Columba livia), Spotted dove (Streptopelia chinensis), Rose ringed parakeet (Psittacula krameri),Common myna (Acridotheres tristis), House crow (Corvus splendens), House sparrow (Passer domesticus), Baya weaver bird (Ploceus philippinus), White throated munia (Lonchura malabarica), and Peafowl (Pavo cristatus) which depredate experimental field crops among them only few birds such as: Rose ringed parakeets, House crows, House sparrows, Pigeons, Baya weavers, Peafowls and Munias were serious bird pests to major agricultural and horticultural crops. The University farm areas were found to be the most preferred habitat for many of these birds, it could be due to availability of food, breeding, roosting and resting sites in abundance because of more agricultural croplands and agro forestry trees.

The Agricultural College, Sircilla of Professor Jayashankar Telangana State Agricultural University, as the sixth and youngest college of the University, started during the academic year 2018-19. One of the mandatory activities of the college in addition to academics is adoption of village and disseminating need based relevant technologies of the University for improvement of livelihoods of the villagers. Hence, a village by name Narsimhulapalle of Thangallapalli Mandal, Rajanna Sircilla district was adopted as part of extension activities of the college which is about 19 km from the college. Prior to the dissemination of improved technologies, the identification of existing scenario in the village with regards to soils, fertility status, crops, varieties, package of production technologies followed were taken up. Soil samples were collected with geo-positions from every farmer’s field i.e., 114 farm holds of the village, processed and tested for fertility status. Action plan was prepared based on crop grown to alleviate the livelihoods of the village. A systematic collection of demographic, socio economic conditions and livelihoods of the villagers from primary and secondary sources along with prevailing farming practices were documented. All the 114 soils of the village were deficient in N, while majority of soils were medium to high with respect to available P and K. The Soil fertility based fertilizer recommendations were advocated to every individual farmer based on their soil test report for the crop grown. Soil fertility maps were prepared and displayed in the village Panchayat. Bridging of the identified extension and research gaps was planned by proposing relevant technological interventions for the enhancement of livelihoods.

Studies on the Effect of Water Stress on Root Traits in Redgram Genotypes

The experiment was conducted during July–November, 2019 at Regional Agriculture Research Station, Professor Jayashankar Telangana State Agricultural University, Palem, Nagarkurnool district, Telangana State, India. The main treatments had five red gram genotypes and water stress levels were taken as sub-treatment in 3 replications in factorial RBD using specialized root structure made with cement bricks. There was great variability in the yield performance of different Redgram genotypes under drought conditions. The experiment was conducted to select genotypes with efficient root architecture and associated traits under drought stress. Root studies were performed with the Delta T automatic root scanner. The SPAD chlorophyll meter was used to measure the SCMR value. The present study results revealed that genotype, Maruti showed significant superiority for character plant height and SCMR under non-stress, mild stress and severe stress conditions. The same genotype showed superior values for main root length under control and mild stress. Whereas, Laxmi recorded the highest plant height under severe stress and the same genotype also showed significant superiority for total plant dry weight, root dry weight and root area under severe stress. The genotype Laxmi showed significant character, root area and diameter superiority under mild stress. ICPL-20176 recorded significant superiority for main root length under severe stress and root tip for mild stress. The identified genotypes can be used as the parents in future drought-proof breeding useful for cultivating in water stress conditions.

Registration of ‘CLL17’ rice

Abstract‘CLL17’ (Reg. no. CV‐160; PI 693941), a high‐yielding long‐grain rice (Oryza sativa L.) cultivar, was developed by the Louisiana State University Agricultural Center at the H. Rouse Caffey Rice Research Station near Crowley, LA, and approved for release in 2020. CLL17 contains the herbicide‐resistant gene for use in the Clearfield rice production system. The Clearfield rice production system is defined as the brand of rice cultivars that are tolerant to imidazolinone herbicides. CLL17 was derived from the cross ‘CL131’/‘Trenasse’. It showed good yield potential and favorable agronomic characteristics in the 2015 Clearfield Preliminary Yield Trial. In 2016, it was evaluated in the uniform regional rice nursery trial across four southern states. From 2017 to 2022, CLL17 was evaluated in 50 replicated trials across 10 locations in Louisiana. Three high‐yielding commercial cultivars were included as checks: ‘Cheniere’, ‘CL153’, and ‘CL111’. The grain yield of CLL17 was 9.0 t ha−1 compared with 8.9 t ha−1 for CL153, 8.3 t ha−1 for CL111, and 8.2 t ha−1 for Cheniere across 25 commercial advanced trials from 2017 to 2020. CLL17 had a similar plant height to CL111, 2‐cm taller than CL153, and 5‐cm taller than Cheniere. It exhibits typical US long‐grain rice cooking quality with intermediate amylose and gel temperature. CLL17 is susceptible to sheath blight [caused by Rhizoctonia solani Kuhn ], resistant to Cercospora spp., leaf blast [caused by Magnaporthe grisea (T.T. Hebert)], and neck blast, and moderately susceptible to bacterial panicle blight (caused by Burkholderia glumae).

Registration of ‘PVL03’ rice

Abstract‘PVL03’ (Reg. no. CV‐159, PI 699656), a Provisia (BASF) long‐grain rice (Oryza sativa L.) cultivar, was developed by the Louisiana State University Agricultural Center at the H. Rouse Caffey Rice Research Station near Crowley, LA, and approved for release in 2020. PVL03 is the third rice cultivar released as part of the Provisia Rice System with resistance to Provisia herbicide, containing the active ingredient quizalofop‐p‐ethyl, an AACase (group 1) herbicide. PVL03 was derived from the cross ‘PVL01’/‘Catahoula’. Testing in the Provisia preliminary yield trial in 2018 and the multi‐location trial in 2019 indicated good yield potential and favorable agronomic characteristics. In 2020, PVL03 was evaluated in commercial advanced replicated trials across six locations in Louisiana. Four high‐yielding commercial cultivars were included as checks: ‘PVL02’, PVL01, ‘CL153’, and ‘Cheniere’. The average grain yield of PVL03 was 9.6 t ha−1 compared with 8.0 t ha−1 for PVL02, 8.1 t ha−1 for PVL01, 9.8 t ha−1 for CL153, and 9.1 t ha−1 for Cheniere. PVL03 was shorter than the previous Provisia cultivar, PVL02. The milled grain length was longer than that of PVL02, with a length‐to‐width ratio of 3.0. It has a typical US long‐grain rice cooking quality with intermediate amylose and gelatinization temperature. PVL03 is moderately susceptible to sheath blight and moderately resistant to leaf blast and bacterial panicle blight.

The Growth and Export Competitiveness of Cotton in India

Cotton production is of paramount importance in India due to its significant impact on various aspects of the country's economy, agriculture, and society. This paper studied the Growth, Instability, and export potentials of cotton in India. This is based on secondary data and data analyzed for three periods viz., Period I (1959-60 to 1978-79), Period II (1979-80 to 1998-99), and period III (1999-00 to 2018-19). The study revealed that the growth of production and productivity of cotton in India increased from periods 1 to 3. The overall period bare that the production growth rate of cotton in India increased significantly by 3.5 percent annually, which is because the productivity rate increased significantly by 2.75 percent per annum, whereas the area also increases significantly at a rate of 0.72 percent annually. The relative contribution of area and price effect was positive with high output growth of cotton due to the development of many policies related to area extension and price policy by the government. The RSCA value in 2012 was -0.02 to -0.08, which would be attributed to an increase in domestic demand and a reduction in ambiguity. The results of RCA revealed that India is leading Agriculture Institutions and state Agriculture Universities should focus on developing as high yielding varieties of cotton for cotton export. The government should also support farmers to increase the export and production of cotton in India.
