An experiment was carried out at the Regional Agricultural Research Station, BARI, Ishurdi, Pabna during 2013-15, with eleven genotypes of plantain to evaluate their performances for yield attributes, yield and quality characters. The genotypes included in this investigation were MP001, MP002, MP003, MP006, MP007, MP015, MP018, MP024, MP025, ISD002 and BARI Kola-2 as check. The experiment was laid out in randomized complete block design with three replications. The genotype MP002 produced the maximum number of fingers/bunch (105.67) closely followed by BARI Kola-2 (103.00) and MP015 (101.00). Both the genotypes MP024 and MP025 showed the highest fruit length (21.70 cm), but ISD002 gave the maximum fruit girth (16.78 cm), which was statistically similar with that of MP003 (16.30 cm) and MP024 (16.33 cm). The highest yield and the maximum number of hands were produced by the genotype MP024 (47.81 t/ha and (8.33/bunch) followed by MP015 (36.70 t/ha and 6.33/bunch). Fingers of the genotypes required boiling time in the range of 20.00 min (MP001) to 15.00 min (BARI Kola-2). Flesh of all genotypes possesses pleasant aroma except MP002, MP003 and ISD002. Among the eleven genotypes MP001, MP006, MP007, MP008, MP015 and MP024 were found better when cooked as smashed. The genotype ISD002 took the maximum time (467.33 days) to reach the edible maturity stage of fruits whereas MP024 required the minimum (339.00 days). The genotypes MP015 and MP024 performed better than BARI Kola-2 in respect of bunch weight, fruit size, productivity index, yield, sucker production and qualitative characters.Bangladesh J. Agril.

A field experiment was conducted at Agricultural Research Station, Baljigapade, Chikkaballapur taluk and district, which comes under the Eastern Dry Zone of Karnataka during Kharif season 2018. The experimental plot in the field was laid out following a randomized complete block design (RCBD) with fourteen treatments and three replications. The treatments included two levels of N and P2O5 (20 and 30 kg ha-1) and three levels of K2O (10,20 and 30 kg ha-1). Farmyard manure was applied at the rate of 6.25 t ha-1 to all the treatments except absolute control. Results indicated that application of 30 kg N+30 kg P2O5+30 kg K2O ha-1 with Farm Yard Manure (FYM) increased the micronutrient availability in soil N (150.29 kg ha-1), P2O5 (17.60 kg ha-1), K2O (160.84 kg ha-1). Application of FYM @ 6.25 t ha-1+30 kg N+20 kg P2O5 +20 kg K2O ha-1 significantly increased growth, yield, macronutrient content and uptake by brown top millet grain and straw against absolute control. The grain yield of browntop millet was increased by 61.46 percent in T10 and 59.07 percent in T9 as compared to the absolute control.

In Southern India, drought stress is a major constraint to chickpea production and yield stability. Drought tolerant index (DTI) that provides a measure of drought based on yield loss under drought condition in comparison to normal condition was used for screening drought-tolerant genotypes. This study was conducted to determine drought tolerant genotypes with high yield in stress and non-stress conditions utilising physiological traits. Thirty chickpea genotypes were tested in a randomized complete block design with three replications under rain fed and irrigated conditions at Regional Agricultural Research Station, Nandyal, Andhra Pradesh, India during rabi, 2018-2019. The analysis of variance carried out for yield and drought tolerant traits revealed highly significant differences among the genotypes for all characters under rain fed as well as irrigated conditions. NBeG 776, NBeG 779, NBeG 868, ICCV 181606, MH 13 and MH 14 are drought tolerant. NBeG 776, NBeG 779 and NBeG 868 are suitable under both rain fed and irrigated conditions with significantly higher yields over their respective means. ICCV 181606, MH 13 and MH 14 are suitable exclusively for rain fed condition with significantly superior yields over the mean.

An experiment was conducted in order to identify the productive genotype of turmeric for the plains of Nepal. In 2017 and 2018, seven promising turmeric genotypes (CI 0207, CI 0205, CI 9102, CI 1312, CI 0503, CI 0507, and CI 0201) were compared with KKH-1 in a Randomized Complete Block Design with four replications at the Directorate of Agricultural Research, Tarahara, Nepal. The plants were 30 cm x 30 cm apart, with 40 plants per 3.6 m2 plot area. Cultural practices were followed in accordance with the recommendations. Analysis of variance, correlation, cluster, and GGEbiplot analysis were performed on the observed data. From the pooled analysis of two years of data, the results showed significant differences in plant height and fresh rhizome yield among genotypes. The rhizome yield of KKH-1 was found significantly higher (19.36 t ha-1) than CI 0205 and CI 9102 and at par with other genotypes. Weight of mother rhizome had significant positive correlation (r = 0.602**) with yield of fresh rhizome. Though KKH-1 yielded the highest fresh rhizome, the cluster and GGEbiplot analysis identified CI0207 as one of the potential turmeric clones next to KKH-1.

A field experiment was carried out to study the “Effects of different maize–soybean intercropping patterns on yield attributes, yield and B: C ratio” at the Agricultural Research Farm, Bhagwant University, Ajmer. Treatment consists of Sole maize (60x20 cm), Sole Soyabean (30x10 cm), Maize-Soybean (1:1) (60X20 cm), Maize-Soybean (1:1) (75X20 cm), Maize-Soybean (1:1) (90X20 cm), Maize-Soybean (1:2) (90X20 cm) and Maize-Soybean (2:6) (Paired row 45/180 cm). There were four replicated blocks and plot sizes measuring 7 m x 4.5 m laid out in a randomized complete block design (RCBD). Results of the experiment showed that the maize-soybean intercropping patterns had significant effect on maize stover and grain yields. Sole maize recorded significantly higher yield than intercropped maize under varying geometry and row proportion. However, it was at par with maize intercropped with soybean in 1:1 row proportion with 60 x 20 cm .The intercropping patterns affected significantly the PAR intercepted and the leaf area index. The soybean sole crop intercepted significantly more light and leaf area index (LAI) than all other treatments and/or crop. Further,, the yield of sole soybean was significantly superior over other intercropped treatments. The highest benefit cost ratio revealed that higher return per unit money invested for inputs used for raising crops. The highest B: C ratio was recorded with maize + soybean in 2:6 paired row (3.57) intercropping system. The least B: C ratio was recorded in sole soybean (2.45).

The purpose of this study was to assess the variation on agro-morphological traits and grain yield. A set of 14 early maize genotypes were studied at research field of Regional Agricultural Research Station (RARS), Doti, Nepal in summer seasons of 2015 and 2016. The experiment was carried out in Randomized Complete Block Design (RCBD) with three replications in each year. The variation among genotypes was observed for grain yield and flowering. The genotype SO3TEY-PO-BM produced the highest grain yield (4.33 t/ha) in 2015 whereas Rajahar Local Variety produced the highest grain yield (2.52 t/ha) in 2016. The combined analysis over years showed that Farmer’s variety was found earlier in tasseling (36 days) and silking (39 days), followed by S97TEYGHAYB(3) in tasseling (45 days) and by S97TEYGHAYB(3) and Arun-4 in silking (48 days). EEYC1 produced the highest grain yield (3.17 t/ha), followed by COMPOL-NIBP (3.09 t/ha), SO3TEY-PO-BM (2.90 t/ha), S97TEYGHAYB(3) (2.78 t/ha) and Rajahar Local variety (2.77 t/ha), respectively. The information on variation for the agro-morphological traits among studied early maize genotypes will be helpful to plant breeders in constructing their breeding materials and implementing selection strategies.

The experiment was conducted for two consecutive rabi seasons of 2005-06 and 2006-07 at the Regional Agricultural Research Station (RARS), BARI, Jamalpur to find out an optimum dose of sulphur for yield maximization of garlic cv. Jamalpur local. There were six levels of sulphur viz., 0, 15, 30, 45, 60, and 75 kg/ha. A control treatment was in the experiment. The experiment was laid out in randomized complete block design with three replications. The fertilizer package N150P60K120Zn4 B1 kg/ha was applied to each plot as blanket dose.  Results revealed that most of the growth and yield parameters increased progressively with increasing rate of sulphur application. Bulb yield increased with successive increase in the level of sulphur up to 45 kg/ha and thereafter decreased. The highest bulb yield (7.05 t/ha in 2005-06 and 7.22 t/ha in 2006- 07) was achieved at 45 kg S/ha and the control treatment receiving no fertilizer had the lowest yield (3.21 t/ha in 2005-06 in and 3.26 t/ha in 2006-07). The yield benefit for 45 kg sulphur per hawas 34.2% in 2005-06 and 40.0% in 2006-07 over no sulphur. Sulphur at 45 kg/ha produced 54.5% and 54.9% higher yield over control treatment in both the years. The optimum and economic dose of sulphur for the yield of garlic were 44.0 and 43.6 kg/ha, respectively. DOI: http://dx.doi.org/10.3329/bjar.v36i4.11751 Bangladesh J. Agril.

Field experiments were conducted during kharif 2013 and 2014 at Agricultural Research Station, Mugad, University of Agricultural Sciences (UAS), Dharwad (Karnataka), to determine the response of zinc applicationon on growth, zinc content and grain yield of rice genotypes and also studied correlation between yield and zinc content. The experiment was comprised of 20 genotypes and three treatments viz., T1: Control (no zinc); T2: Soil application of ZnSO4 (20 kg ha-1) T3– Foliar Spray of ZnSO4 @ 0.5% at 50% flowering, laid out in factorial randomized block design with two replications. The data revealed that application of ZnSO4 recorded significantly higher plant height (85.9 cm), leaf area (764.5 cm-2 plant-1), number of tillers (95.4 m-1), total dry weight (26.1 g plant-1), panicle weight(15.3 g plant-1), number of panicles (81.6 m-1) and grain yield(3966 kg ha-1) over the foliar application of Zn and control . However number of grains panicle-1 (97.8 panicle-1), test weight (23.7 g), shoot and seed zinc content (15.9 and 21.2 ppm, respectively) were increased with foliar application of Zn. Correlation studies classified the genotypes as high seed zinc content (> 21 ppm) and low seed zinc content genotypes ( less than 21 ppm). High and low seed zinc content genotypes showed negative correlation with yield and yield attributes. However, shoot zinc content was positively correlated with yield.
