Insights from Morpho-Physiological Traits Imparting Tolerance for Preharvest Sprouting of Mungbean Genotypes

Due to the absence of fresh seed dormancy (FSD) in mung bean seeds makes them susceptible to pre-harvest sprouting (PHS). Mung bean yield has been proved to be 60–70% reduced in response to PHS, an abiotic stress. By understanding this problem present study was carried out at at experimental field, Department of Agricultural Botany (Plant Physiology) (20.70060N, 77.03710E), PGI, Dr. Panjabrao Deshmukh Krishi Vidyapeeth, Akola during kharif (rainy) season 2012-13. The experiment entitled “Insights from morpho-physiological traits imparting tolerance for preharvest sprouting of munbean genotypes”. The design of experiment is Randomized block design in three replications with sixteen genotypes. It was observed that on the basis of morpho-physiological traits viz., high hard seed %, pod pubescence, lower germination in pod and seed, less seed and pod moisture genotype AKM-9801, AKM-9907, BM-2002-1 and AKM-10-05, genotypes were found to be tolerant to preharvest sprouting. And more interesting fact is the seed yield per hector found efficient in AKM-8802 and AKM-9907. So, it was found that AKM 9907 is best suitable variety of mungbean in kharif season to prevent crop from whether damage and improve yield also.

Quantifying response of azospirillum and phosphate solubilizing bacteria liquid inoculants seed treatment on productivity and profitability of kharif grain sorghum (Sorghum bicolor)

A field study was carried out during 2017–19 at Sorghum Research Unit, Dr. Panjabrao Deshmukh Krishi Vidyapeeth, Akola, Maharashtra to assess the effect of liquid bio-fertilizers inoculation over existing powder form inoculants on kharif grain sorghum [Sorghum bicolor (L.) Moench]. The experiment comprised of 6 treatments, viz. no bio-fertilizer control i.e. with RDF alone (T1 ); RDF + Azo. (Azospirillum) + PSB @50 g each/kg seed (T2 ); RDF + Azo. + PSB @2 ml each/kg seed (T3 ); RDF + Azo. @2 ml and PSB @4 ml/kg seed (T4 ); RDF + Azo. @4 ml + PSB @2 ml/kg seed (T5 ); and RDF + Azo. + PSB @4 ml each/kg seed (T6) conducted in randomized block design (RBD) with 4 replications. Pooled data revealed that seed inoculation with Azo. + PSB @2 ml each/kg seed (T3 ) has improved the sorghum biological, grain yield and net returns 21.13, 19.83 and 17.92% over their powder form of inoculants i.e. T2 (14.71 t/ha, 3.56 t/ha and 73,116). These enhancements in biomass, grain yields and net income was owing to liquid bio-fertilizer seed treatment. Liquid-based inoculants were found to boost growth and yield parameters, which was ascribed to the concomitant increase in plant height and number of grains/panicle, respectively. Increase in quantity of liquid bio-fertilizers beyond 2 ml/kg seed proved not-rewarding from both productivity and profitability point of view. Sorghum seed inoculation with liquid bio-fertilizers @2 ml each/kg seed proved to be a potential substitute for existing powder form without any additional cost.

Influence of Organic, Inorganic, and Foliar Grade Fertilizers on the Growth and Yield of Groundnut

Optimizing mineral nutrition is crucial to boosting groundnut output since groundnut have a high nutritional requirement and the recently released high yielding varieties further absorb nutrients from the soil. On the other hand, farmers that grow groundnut sometimes employ only one or two nutrient-rich fertilizers, which results in severe mineral deficits. One of the primary reasons for low groundnut productivity is inadequate and imbalanced nutrient usage. At the Oilseeds Research Unit, Dr. Panjabrao Deshmukh Krishi Vidyapeeth, Akola, Maharashtra, India, a field experiment was carried out in the summer to assess the effects of organic, inorganic, and foliar grade fertilizers on the growth and yield of groundnut. The integration of organic, inorganic, and foliar grade fertilizers considerably improves growth and yield qualities, according to experimental data. The findings showed that the application of FYM @ 7.5 t ha-1+100% RDF 25:75:25 NPK kg ha-1 considerably improved plant growth parameters, such as plant height and yield attributes yield. Starter dose (11:36:24 NPK + trace element) + booster dose (8:16:39 NPK + trace elements) applied topically. It was determined that integration of organic (7.5 t ha-1), inorganic fertilizer (100% RDF), and water soluble grade fertilizer recorded, highest dry pods yield and getting maximum economic return from summer groundnut. This treatment was closely followed by treatment FYM @ 7.5 t ha-1+100 % RDNPK, which recorded significant pod yield (27.18 qt ha-1), net monetary return (79464 Rs. ha-1) and benefit: cost ratio (2.77).
