Effect of Sulphur Levels on Grain Yield of Clusterbean  [Cyamopsis tetragonoloba (L.) Taub.] under Rainfed Condition in Hanumangarh District of Rajasthan

Insufficient stand establishment of winter wheat is a major problem in the rainfed region of the Uttarakhand hills. In order to increase germination and early establishment in the field under rainfed condition of hilly tracts this study was conducted at college of forestry VCSG University of Horticulture and Forestry, Ranichauri, Tehri Garhwal, Uttarakhand, India. The ten treatments were laid out in randomized block design with three replications in field. The treatments were VL 892 primed for 12 hrs with normal water, VL 892 primed for 24 hrs with normal water, VL 892 primed for 12 hrs with lemon water, VL 892 primed for 24 hrs with lemon water, VL 829 primed for 12 hrs with normal water, VL 829 primed for 24 hrs with normal water, VL 829 primed for 12 hrs with lemon water, VL 829 primed for 24 hrs with lemon water, VL 892 with no priming, and VL 829 with no priming. Significantly higher grain Yield of wheat was recorded in VL 829 primed with normal water for 24 hours which was statistically on par with VL 829 primed for 12 hrs with normal water, VL 892 primed for 24 hrs with normal water and VL 892 primed for 12 hrs with normal water. Significantly higher grain yield was recorded in case of priming with normal water than the priming with lime water.

In the present study, performance of five promising soybean genotypes over 4 locations during kharif 2013, 2014 and 2015 were investigated using GGE biplot analysis. Location attributed the highest proportion of the variation for all the traits except 100 seed weight ranging from 26.97-86.81% whereas, genotype contributed only 3.01-60.51% and genotype x location interaction contributed 6.01-31.42% of total variation. For 100 seed weight genotype has contributed major proportion of variation (66.26%) than location (31.08%) and genotype x location interaction (2.65%). Superior genotypes for key traits viz., grain yield (VLS 86) and 100 seed weight (Himso 1685) were effectively identified using GGE biplot graphical approach. It may be stated from present study that, VLS 86 was the closest to ideal genotype with stability for high grain yield as well as earliness. ‘Which-won-where’ study partitioned the testing locations into two mega-environments: first with three locations with VLS 86 as the winning genotype; second mega environment encompassed only one location with Himso 1685 as the winning genotype. Existence mega environments was found correlated with the rainfall pattern and clearly suggested that different entries need to be selected and deployed for realising maximum grain yield in hill zone.

Randomized Complete Block Design

Two field experiments were carried out at farmer’s field of Rajshahi and Chapainawabgonj under the Department of Agronomy, BINA during aman season of 2017 and 2018 consecutively to evaluate the drought tolerant rice varieties under different establishment methods in rain fed condition. First experiment (E1) was conducted to find out the performance of varieties and second experiment (E2) was to find out the suitability of method of transplanting/sowing in combination with short duration aman varieties. Different methods were as direct seeding, puddled and un-puddled transplanting and cultivars were used to cultivate BRRI dhan56, Binadhan-7, Binadhan-17 (except in second experiment) and Huttra (local cultivar). The experiment was laid out in a randomized complete block design with three replications. The recommended fertilizer doses applied for the experiment were 80 kg N ha-1, 15 kg P ha-1, 50 kg K ha-1, 20 kg S ha-1 and 2 kg Zn ha-1. Nitrogen, phosphorus, potassium, sulphur and zinc were supplied from urea, TSP, MoP, gypsum and zinc sulphate monohydrate respectively while urea was applied in three equal splits. Among the cultivar Binadhan-17 produced statistically higher grain yield (5.62 t ha-1) at Chapainawabgonj. Among methods Binadhan-7 statistically higher grain yield 5.32 t ha-1 and 5.21 t ha-1, respectively) in puddle transplanting method both Chapainawabgonj and Rajshahi region during 2017. Among the cultivar Huttra (local) produced statistically higher grain yield (5.43 t ha-1) at Chapainawabgonj. Among methods, BRRI dhan56 statistically higher grain yield 6.37 t ha-1 and 6.19 t ha-1, respectively) in puddle transplanting method bothat Rajshahi and Chapainawabgonj during 2018. Overall results indicates that BRRI dhan56, Binadhan-7, Binadhan-17 performed better in puddled transplanting, Huttra (local) in direct seeding method in drought prone region of Bangladesh.

Different Altitudes

To evaluate high yielding drought tolerant rice varieties in different altitudes, a field experiment was carried out at Duradanda, Lamjung, Nepal during rainy season of 2016 under rainfed condition. The experiment was laid out in a factorial randomized block design with two replications. The treatments comprised of six different rice varieties viz. Sukhadhan-1, Sukhadhan-2, Sukhadhan-3, Sukhadhan-4, Sukhadhan-5 and Sukhadhan-6 and four altitudes viz. 1000, 1200, 1400 and 1600 masl. The results revealed that rice variety Sukhadhan-2 produced the highest grain yield (2.93 t/ha) followed by Sukhadhan-5 (2.92 t/ha) and Sukhadhan-3 (2.82 t/ha). The highest grain yield of Sukhadhan-2 was due to higher number of effective tillers/m2 (228), higher number of grains/panicle (83), higher panicle length (21.79 cm) and low sterility percentage (27.91%) as compared to other varieties. Regarding to altitudes, the highest grain yield (3.34 t/ha) was obtained in lower altitude (1000 masl) followed by 1200 masl (2.79 t/ha), 1400 masl (2.68 t/ha and 1600 masl (1.85 t/ha). The lower yield in higher altitude was due to higher sterility percentage, less number of effective tillers per unit area and less number of effective grains per panicle. It seems that the performance of these varieties was good up to 1400 masl.

Genotypic Effects

A set of twenty wheat (Triticum aestivum L.) genotypes was evaluated to assess morpho-physiological, yield and yield attributing traits related to post-anthesis drought in wheat genotypes under rainfed condition in a Randomized completely block design with three replications at research farm of Faculty of Agriculture, Rampur, Chitwan, during winter season of 2016/2017. The result revealed highly significant genotypic effects for number of tillers per m2 area, plant height, spike length, number of grains per spike, weight of grains per spike, 1000 kernels weight, days to booting, days to heading, days to anthesis, days to flag leaf senescence, days to maturity, SPAD meter reading, peduncle length, grain filling duration and reproductive growth period. Significant genotypic effects were found for grain yield, biological yield and harvest index and an array of variation was found among the genotypes for each trait. But non-significant genotypic effect was found for canopy temperature depression. WK2373 gave highest grain yield kg/ha (3035 kg/ha) and biomass yield kg/ha (8080 kg/ha). This study presented WK2373, WK2379, WK2380, WK2386, WK2388, WK2383, WK 2378 and WK1481 the best genotypes governing different valuable traits. These potential genotypes for valuable traits found in different clusters. Crossing genotypes belonging to different clusters could maximize the opportunities for transgressive segregation as there is a higher probability that unrelated genotypes would contribute unique desirable alleles at different loci. Therefore, this study can help breeders to increase genetic diversity by selecting materials of divergent parentage for crosses, thereby reducing vulnerability to diseases and climate changes. Int.

Root Treatment

In the Southern Federal District, there is a high interest in guar - a new leguminous crop for Russia. The purpose of the research is to study the effect of fertilizers containing trace elements on the productivity of guar grain on ordinary chernozem in the conditions of the Lower Don. On average for 2017–2019, when growing guavar varieties Vavilovsky 130 for grain the highest yield of 1.56 t / ha was obtained when three-term (in the phases of budding, flowering and seed formation) complex fertilizer Ecogrinvit bean was applied. The effect of fertilizers amounted to 183.6%. All foliar micronutrient feeding separately was significantly less effective. Noteworthy is the option with non-root treatment of guar plants with zinc. When a dose of Zn60 was applied, the effect of fertilizer was 109.8%. Twofold application in the total dose of B270 allowed one to obtain the effect of making 94.1%, while the grain yield exceeded the control by 0.48 t / ha. In the conditions of the Lower Don, microelements introduced as foliar top dressing act on guar plants not only as nutrients, but also as fungicides.
