Out of the five cultivars, Okura gave significantly the highest of Root wt. (326 g), Root yield (53.85 t/ha), Root length (25.5 cm), Root diameter (53.9 mm), and Leaf wt per plant. (268 g), Days to harvest (63 days) followed by Miyasige which had Root wt (259 g), Root length (23.4 cm) Root diameter (51.9 mm), Days to harvest (66 days). Okura had 49 percent yield increment followed by Miyasige with 21.9 percent as compared to Mino Early. Hence, these two cultivars are found superior and recommended for cultivation in central mid-hills like Kathmandu valley conditions in Nepal.

Effect of Different Levels and Time of Application of Paclobutrazol on Morphology, Yield and Yield Attributing Characters and Economics of Groundnut (Arachis hypogaea L.)

Background: Groundnut is one of the most important oilseed crops of Odisha and grown in both in kharif and rabi-summer seasons. Because of excessive vegetative growth in kharif season, the yield potential is lower than rabi-summer resulting in low yield. Keeping this in view, an experiment was set up to investigate the effect of different concentration and time of paclobutrazol application on growth and yield of groundnut.Methods: A field experiment was conducted during kharif 2016 to 2018 at AICRP on Groundnut Research Farm, OUAT, Bhubaneswar, Odisha. The experiment was laid out in split plot design with different concentration of paclobutrazol in main plot and time of application in sub plot and replicated thrice. Recommended dose of 20:40:40 kg of N, P2O5 and K2O entirely applied as basal. Yield and yield attributing characters were taken at the time of harvest.Conclusion: Application of paclobutrazol at different concentration significantly reduced groundnut plant height and significant reduction was observed with application at 30 DAE. Among various yield attributing characters; pod/plant and pod yield increased significantly (24.6% and 27.4%, respectively) with application of paclobutrazol @ 100 ppm with higher benefit cost ratio of 1.97 and upto (8.4% and 17.5%) with application at 30 DAE.

Study of Urea Embed Mesoporous Nano Silica on Yield and Yield Attributing Characters of Rice Grown in Mollisols

Rice (Oryza sativa L.) is a stable food more than two billion people are getting 60-70 per cent their energy requirement from rice and its derived products. Present research investigated effect of urea embed mNS (embed in the mesoporousnano silica by simple immersion loading using aqueous solution and this formulation of nanofertilizer) on rice crop in pot experiment under polyhouse condition. Nine treatments consisted (T1: Control, T2:N30P60K40,T3:N60P60K40, T4:N90P60K40, T5:N120P60K40, T6:N30(mNS)P60K40,T7:N60(mNS)P60K40, T8:N90(mNS)P60K40 and T9:N120 (mNS)P60K40.) in three replications. In this study, the results revealed that the growth parameter, grain and straw yields as well as yield attributes (effective tillers, panicle length, grains per panicle and 1000-grain weight) were significantly affected by urea embed nano silica application. The highest grain and straw yields were recorded in treatment T9 giving 323.02 and 124.05 per cent more over control, due to exposure of urea embed mNS as compared to ordinary urea dose of chemical fertilizers. The sustained release of urea embedded mNSaccurs 7-8 days after exposure which is extraordinarily slow as compared to ordinary urea. These results are preliminary but promising and open the doors to use nanomaterials as an efficient nanofertilizer.

The field experiment was conducted during 2013-2014 at Nagarjuna Medicinal Plants Garden, Dr. Panjabrao Deshmukh Krishi Vidyapeeth, Akola (M.S.) There were three levels of FYM and four levels of fly ash with three replications in FRBD on Inceptisol with a view to study the effect of FYM and fly ash application on yield, quality and nutrient uptake of safed musli. As the physiological maturity of the crop begins at 85-90 days after sowing (DAS) the growth observations e.g. number of leaves, leaf area were recorded at 30, 60 and 90 days after sowing. The number of leaves were successively increased with each growth stage upto 60 days Significantly highest leaf area was recorded with the application of 20 t FYM ha-1 (M2) .Significantly highest leaf area (29.56 cm2) was recorded at 60 DAP with the application of 15 t fly ash ha- 1 which was at par with 10 t fly ash ha-1 (F2) and 5 t fly ash ha-1 (F1). Significantly highest dry matter accumulation was recorded with the application of 20 t FYM ha-1, however, it was at par with 10 t FYM ha-1. The highest biomass accumulation was observed with 15 t fly ash ha-1 (F3) which was at par with 10 t fly ash ha-1 (F2) and 5 t fly ash ha-1 (F1). The thermal industrial waste like fly ash showed a promising option for nutrient management in medicinal crop plant like safed musli which can substitute to some extent costly chemical fertilizer and improve the qualitative value of safed musli.

Yield and Yield Attributing Characters of Promising Rice Genotypes under Dry Direct Seeded Conditions as Affected by Varieties and Weed Control Methods

Dry direct seeded rice is an alternative to the farmers in the context of climate change and inputs scarcity especially labor. However, weeds are the major problem in dry direct seeded conditions competing with the different resources provided to the crop. Hence, field experiments were conducted for two consecutive years 2015 and 2016 in the experimental field of Rice Research Program, Hardinath, Dhanusha to identify the appropriate herbicides for DSR. The experiment was laid out in a split plot design and treatments were replicated thrice. Three varieties of rice namely Ciherang Sub-1, IET 16775 and Sukhkhadhan-3 were treated as main plot factors while five levels of weed control methods (Oxadiargyl @ 100 g a.i./ha as pre-emergence followed by Fenoxaprop @ 90 g a.i./ha with safener, Pendimethalin @ 1000 g a.i./ha as pre-emergence followed by Bispyribac sodium @ 25 g a.i/ha at three weeks after seeding, Pendimethalin @ 1000 g a.i./ha as pre-emergence followed by Pyrazosulfuron ethyl @ 25 g a.i.ha + Bispyribac sodium @ 25 g a.i./ha at three weeks after seeding, hand weeding and weedy check) were treated as sub-plot factors. The statistical analysis showed that the effect of weed control methods on yield and yield attributing parameters of the tested rice varieties was significant. Out of the tested treatments hand weeding yielded significantly higher grain yield (5.4 t/ha) followed by herbicides Pendimithalin fb Pyrazosulfuron ethyl + Bispyribac sodium; which reduced the weed density and was comparable with hand weeding. The interaction effect of weed control methods and varieties was found non-significant. Pendimithalin fb Pyrazosulfuron ethyl + Bispyribac sodium was found to control broad spectrum of weeds and also reduced the human labour drudgery and increasing the rice yield than the other herbicides in direct seeded rice.

Effect of nitrogen level on growth and yield attributing characters of radish

Radish is one of the well-known root crops that belong to family Brassicaceae. Its popularity could be due to its wider climatic adaptation, easy cultivation methods and wider ranges of its uses. The cultivar “Minow Early” was selected for experiment. Field trial was conducted on horticultural farm of Lamjung campus between October to January 2017/18 in Randomized Complete Block Design with four replications and five treatments to assess the role of five different levels of nitrogen (100, 150, 200, 250 and 300 kg per ha) application on growth and yield attributes of radish. The different growth and yield parameters such as plant height, number of leaves, root length, root girth, root weight were measured. Significant differences were found on root length and plant height. Maximum root length and plant height was observed at 250 and 300 kg per ha reflecting better yield performance in these levels of nitrogen. This indicates that 250 kg per ha of nitrogen was best for better yield (mean root weight =121.3 g per plant).
