Field experiment on cultivar mixture was conducted for trailing type and bushy type bean (Phaseolusvulgaris L.) to know the effect of cultivar mixtures on grain yield and disease infection during summer season 2015 in Jumla. The result of the study revealed that agronomic attributes were enhanced while Anthracnose infection was reduced under cultivar mixtures of bean than those of their sole cropping both for trailing type and bushy type beans under study. Agronomy Journal of Nepal (Agron JN), Vol.4, Page: 128-135, 2016

SUMMARYRhizobium strains adapted to high temperature, and genotypes of green gram, were used to study the symbiotic N2-fixation in a summer season at two moisture levels in calcareous soil. Different interactions between strains and genotypes were observedatthe two moisture levels. At both moisture levels, strain S4 with the green gram genotype S8 showed the greatest grain yield, nitrogenase activity, leghaemoglobin and ethanolsoluble carbohydrate of nodules.

A field experiment was conducted at the farm of Bangladesh Agricultural University, Mymensingh during November 2009 to March 2010 to study the response of three lentil varieties (viz., BARI Masur-1, BARI Masur-2 and BARI Masur-3) to Rhizobium inoculations to yield. There were three Rhizobium inoculants (Rhizobium strain BINA L4, Rhizobium strain TAL 640, and mixed culture) with uninoculated control and urea @ 50 kg ha-1. Phosphorus and potassium @ 26 kg P ha-1from TSP and 33 kg K ha-1 from MP were used as basal. It was observed that Rhizobium inoculation alone increased plant height, grain yield and crop residues yield of plant significantly compared to uninoculated control. Local inoculants BINA L4 performed better than the exotic culture TAL 640 in respect of yield. 50 kg urea ha-1 also recorded better results than control but not superior to any of the inoculation treatments. The highest seed (1,565 kg ha-1) and crop residue yields (3,303 kg ha-1) were recorded from the lentil variety BARIMasur-3 inoculated with mixed culture.Bangladesh Agron. J. 2014, 17(1): 41-46

The present study pertaining to the identification of high yielding quality protein maize genotypes was conducted under coordinated varietal trials (CVT) at Khumaltar (Lalitpur) and Kabre (Dolakha) from 2011 to 2012 summer season and under coordinated farmers' field trials (CFFT) at Lumle (Kaski), Kimugaun (Dailekh) and Kabre (Dolakha) in 2011 summer season and at Dailekh and Kabre in 2012 summer season. The results of these trials showed that the genotypes namely Obatanpa followed by S99TLWQ-B and S01SIYQ produced the highest grain yield under coordinated varietal trials and genotypes namely S99TLYQ-B followed by S01SIWQ-3 and Poshilo Makai-1 produced the highest grain yield under coordinated farmers' field trials across testing sites and years. It is suggested that the superior genotypes derived from CFFT could be released and then recommended to farmers of mid hills of Nepal.International Journal of Life Sciences 10 (1) : 2016; 7-9

A field experiment was conducted at Badgingarra, W.A., during 1981 to study competition between wheat (cv. Gamenya) and great brome (Bromus diandrus Roth.). Shoot dry matter per plant of wheat was reduced from 1.41 g per plant in wheat monoculture to 0.50 g per plant after competing for 71 days with great brome at density of 400 plants m-2. Tiller production was reduced from 605 tillers m-2 in monocultures of wheat to 336 tillers m-2 when growing in association with 400 plants m-2 of great brome. Competition with great brome reduced the concentration of nitrogen and phosphorus in wheat shoots; at Feeke's scale 3 (tillers formed) wheat plants competing with 400 plants m-2 of great brome had 3.15 � 0.09% (mean � s.e., w/w) nitrogen and 0.58% phosphorus against a concentration of 4.05 � 0.1% nitrogen and 0.77% phosphorus in the monoculture of wheat. The reduction in the nitrogen - and phosphorus concentrations in wheat shoots earlier than any significant reductions in their dry matter suggested that great brome competed with wheat for absorption of nitrogen and phosphorus. Competition with great brome also resulted in significant reduction in the grain yield (r = - 0.77) and yield determinants of wheat. Reduction in mass per grain (r = - 0.77) was probably due to competition with great brome for water during grain-filling.

AbstractThe aim of the study was to evaluate the effect of nitrogen (N) and sulphur (S) fertilizers on the content and uptake of macronutrients by grain dry mass (DM) of spring wheat. A field experiment was conducted in southeastern Poland on Cambisols (WRB 2007), in conditions of low S content in the soil. The experiment included 2 factors: fertilization with N (0, 40, 80, 120 kg ha-1) and with S (0, 50 kg ha-1).The experiment showed a positive response of spring wheat to N and S fertilization. The highest grain yield was found after application of 80 kg N ha-1 and addition of 50 kg S ha-1 (5.43 t ha-1). The described combination resulted in beneficial content of phosphorus (P), potassium (K), magnesium (Mg), calcium (Ca) (P –4.267, K–4.533, Mg–1.567, Ca–0.433 g kg-1) and uptake of macroelements by grain dry mass (DM) (P–20.48, K–21.79, Mg–7.52, Ca–2.08 kg ha-1). A generally positive correlation was found between content and uptake of macronutrients with exception of P content. Fertilization with N caused significantly narrowed mass ratios of K+: Ca2+, K+: Mg2+ and mass and mole ratio of K+:(Ca2++Mg2+) and increased mass ratio of Ca:P. While S application narrowed significantly, mass ratios of K+:Ca2+ and K+: (Ca2+ + Mg2+) and increased mass ratio of Ca:P.

SUMMARYA field experiment conducted for two cropping seasons (1976–7 and 1977–8) showed that a fodder crop of Egyptian clover (Trifolium alexandrinum) increased the grain yield of a subsequently grown maize crop. Lathyrus (Lathyrus sativus) and peas (Pisum sativum) were less effective in this regard.

A field experiment was conducted during kharif season 2015-16 to study the response of rice varieties to different sowing windows under Konkan conditions. The experiment was laid out in split plot design with three replications. The main plot treatments were three sowing windows, viz., 23rd Met Week, 24th Met Week, 25thMet Week. The sub plot treatments comprised five rice varietiesviz., Karjat-5, Palghar-1, Jaya, Swarna and Karjat-2. Thus there were 45 treatment combinations. Results revealed that rice crop sown on 23rd Met. Week recorded significantly higher grain yield (5782 kg ha-1) and straw yield (6462 kg ha-1). Long duration rice variety Swarna recorded the maximum grain yield (5782 kg ha-1) as well as straw yield (6462 kg ha-1), which was significantly higher over all other varieties under study except variety Jaya which was at par. From the present investigation it can be concluded that kharif rice in Konkan be sown during 23rd meteorological week with rice variety Swarna followed by conventional variety Jaya, so as to obtain higher yield and economic returns

A field experiment on evaluation of biopesticides against gram pod borer (Helicoverpa armigera Hub.) on pigeon pea was carried out during kharif season of 2012-13. The experiment was laid out in randomized block design with three replications. Gram pod borer is a major pest of pigeon pea in India. For the management of this pest seven biopesticides were tested along with control. Among the biopesticides, Beauveria bassiana @ 1 liter / ha (1x1012 spores/ml) was found to be most effective biopesticide as it recorded lowest larval population (6.68 larvae / 5plants). The highest larval population was recorded in control (12.61 larvae /5 plants). The least effective treatment was Paecilomyces fumosoreseus (9.31 larvae /5 plants). Similar trend was observed in the grain yield as 1667.55 kg/ha, 709.41kg/ha and 1025.21kg/ha , respectively.

Data from a field experiment on Real Time Nitrogen Management (RTNM) in rice revealed that variety Gobinda produced significantly the highest grain yield of 49.6 q ha-1 associated with long panicle (26.75 cm) bearing significantly the maximum number of filled grains panicle-1 (156.78) producing highest net return (Rs.33214.71), B-C ratio (1.83) and return per rupee invested (0.83). Application of nitrogen based on LCC threshold value 4 produced significantly the highest grain (52.6 q ha-1), straw yield (64.4 q ha-1), number of EBT m-2 (403.71), panicle length (25.43 cm) and 148.94 filled grain panicle-1. Variety x RTNM interaction was significant and variety Naveen and Gobinda produced significantly the highest yield of 55.4 and 58.2 q ha-1 at recommended of nitrogen whereas, Lalat and Hiranmayee responded to LCC threshold value 4 (N4) with grain yield of 50.4 and 52.1 q ha-1, respectively.
