A field experiment was conducted during kharif 2014 - 2015 in the Agricultural Research Station, Adilabad, Telangana to assess the effect of straw mulch and anti – transpirants on growth and yield of soybean. The treatment consisted of A) Anti- transpirants (5) (spray at 15 days after flower initiation): T1 - MgCO3 @ 5% T2 Glycerol @ 5% T3 - KNO3 @ 1% T4 - NaCO3 @ 5% T5 - Control (water spray) B). Straw mulch @ 5 t/ ha after sowing C) Control (no mulch). Among the different anti - transpirants, Na2CO3 @ 5% recorded higher mean seed yield (2862 kg/ ha) which was at par with Glycerol @ 5% (2762 kg/ ha) and MgCO3 @ 5% (2731 kg/ ha). Mulch (straw mulch @ 5 t/ ha) was significantly superior over control (without mulch) with highest mean seed yield (2723 kg/ ha). The combination of straw mulch and anti – transpirant can be recommended as an effective with respect to yield and cost for the soybean under rainfed condition.

Field experiments were conducted at the Regional Agricultural Research Station of Bangladesh Agricultural Research Institute, Jessore during rabi (winter) seasons of 1999-2001 to study the tillage and mulching effects on conservation of residual soil moisture, yield attributes and yield of mustard (cv. Daulat.). Three different tillage methods, namely minimum, reduced and conventional tillage were used in the main plots and three different mulch materials, namely rice straw, water hyacinth, black polythene including no mulch were used in the sup-plots. It was observed that reduced tillage and polythene mulch or rice straw mulch conserve more moisture than other tillage methods and mulch application. Tillage practice significantly influenced the dry matter, yield and yield components of mustard. Reduced tillage gave consistently the highest seed yield (969 kg/ha), while minimum tillage gave the lowest seed yield (92 kg/ha). Mulching also resulted in better crop growth and increased yield. Significantly higher seed yield (1164 kg/ha) was recorded from black polythene mulch followed by rice straw mulch (1089 kg/ha). The yield of mustard was obtained due to the interaction effects on reduced tillage and polythene mulch followed by conventional tillage and polythene mulch, which was found superior to all other treatments. Results revealed that polythene mulch or rice straw mulch accompanied by reduced tillage was economically profitable for mustard cultivation/production under rainfed condition. Key Words: Rainfed mustard, tillage, mulching. doi: 10.3329/bjar.v33i4.2303 Bangladesh J. Agril. Res. 33(4) : 597-606, December 2008

Background: Mungbean is a short duration grain legume widely grown in south and Southeast Asia. The extent of variability through Principal Component Analysis (PCA) and cluster analysis in promising mungbean genotypes should be known for possible yield improvement. A study was undertaken to work out the extent of variability among twenty four mungbean genotypes through cluster analysis and Principal Component Analysis (PCA). Methods: The experiment was laid out in a randomized block design with three replications during kharif 2018 and 2019 at the experimental field of Agricultural Research Station, Navgaon (Alwar) under rainfed condition. Result: Principal component analysis revealed that the first three main PCAs amounted 78.80% of the total variation among genotypes for different traits. Out of total principal components, PC1 accounts for maximum variability in the data with respect to succeeding components. Number of branches per plant (28.62%), number of clusters per plant (23.55%) and seed yield (15.58%) showed maximum per cent contribution towards total genetic divergence on pooled basis. Cluster analysis showed that genotypes fall into seven different clusters and their inter and intra cluster distance showed genetic diversity between different genotypes. The maximum number of genotypes i.e., 8 was found in cluster II followed by cluster III comprising of 6 genotypes. Genotypes RMG-1138 and IPM-02-03 representing the mono genotypic cluster signifies that it can be the most diverse variety and it would be the appropriate genotype for hybridization with ones present in other clusters to tailor the agriculturally important traits and ultimately to boost the seed yield in mungbean under rainfed conditions.

The growth and yield characters of chickpea varieties suitable for mechanical harvesting were evaluated through field experiment conducted for three consecutive years (2016__17 to 2018__19) during rabi season on vertisols under rainfed conditions at Regional Agricultural Research Station, Nandyal, Andhra Pradesh. The investigation was carried out in split plot design with three replications. Two plant geometries (30.0 × 10.0 cm and 22.5 × 10.0 cm) were assigned to main plots and six chickpea varieties (viz., GBM 2, Dheera, CSJ 515, HC 5, Phule G 08108 and BRC 1) were assigned to sub plots. Pooled analysis of experimental results indicated that significantly higher number of branches per plant (8.7) and number of pods per plant (31.1) and test weight (24.3 g) were observed under 30.0 × 10.0 cm when compared to 22.5 × 10.0 cm. Higher plant height (44.8 cm), height of lowest pod bearing branch (30.0 cm), lower days to 50 % flowering (42.1 days) and higher test weight (31.2 g) were observed in Dheera. Higher number of branches per plant (9.2) and number of pods per plant (34.2) were observed in GBM 2. Higher seed yield was observed in Phule G 08108 (1708 kg ha-1) which is followed by GBM 2 (1675 kg ha-1) Dheera (1569 kg ha-1) and BRC 1 (1493 kg ha-1). Higher harvest index (56.4%) was also observed in Phule G 08108. Chickpea varieties GBM2, Dheera and BRC1 were best suitable for mechanical harvesting and higher seed yield due to their excellent morphology.

An experiment was conducted at Regional Agricultural Research Station, Jashore, Bangladesh during rabi season of (2019-2020) to evaluate the effect of foliar application of urea on growth and yield of short durative lentil variety (BARI Masur-9). The experiment was conducted in split plot design with three replications where time of urea spraying, P1= at branching stage, P2= at pod initiation stage were distributed in main plots and doses of urea spraying T1= application of 100% recommended fertilizers as basal except urea, T2= application of 100% recommended fertilizers as basal, T3= application of 75% of urea with 100% of other fertilizers as basal and rest of the 25% of urea by spraying, T4= application of 25% of urea with 100% of other fertilizers as basal and rest of the 75% of urea by spraying, T5= application of 50% of urea with 100% of other fertilizers as basal and rest of the 50% of urea by spraying were distributed in sub plots. The highest plant height, number of pods per plant were obtained from application of 75% of urea with 100% of other fertilizers as basal and rest of the 25% of urea spraying at pod initiation stage. The highest seed yield was also found from application of 75% of urea with 100% of other fertilizers as basal and rest of the 25% of urea spraying at pod initiation stage followed by application of 100% recommended fertilizers as basal and application of 50% of urea with 100% of other fertilizers as basal and rest of the 50% of urea by spraying at branching stage. Plant height, pods per plant and days to maturity showed positive correlation with seed yield. On the other hand days to flower and plants per m2 has no linear relationship with seed yield. The highest marginal benefit cost ratio (3.29) was recorded from application of 75% of urea with 100% of other fertilizers as basal and rest of the 25% of urea by spraying at pod initiation stage. So based on findings to increase the yield potential of BARI Masur-9 foliar application of urea may be a tool and hence application of 75% of urea with 100% of other fertilizers as basal and rest of the 25% of urea by spraying at pod initiation stage may be consider as the best treatment.

The present investigation was carried out during kharif-2012, 2013 and 2014 under rain fed condition at the Agricultural Research Station, Kalaburagi located in north eastern dry zone (Zone 2) of Karnataka, to know the stability and path analysis of the twenty genotypes of pigeonpea including check WRP-1. Highly significant differences among genotypes were observed for all the characters except primary branches. Environmental + (Genotype × Environment) interaction was significant for days to maturity, primary branch, pod bearing length, and seed yield per plant. The variance due to pooled deviation was highly significant for all the characters except for primary branches, pod length and number of seeds per pod which reflect the presence of sufficient genetic variability in the material. Out of 20 genotypes studied, RVK-275 (X=38.713, bi=1.7 and S2di = -9.67) and AKT-9913 (X =43.397, bi=2.86 and S2di= -7.42) were found to be a stable for seed yield and test weight, across the environments with good stability under rain fed conditions compared to local check. Path analysis revealed that days to flower initiation (3.942 and 1.123), days to maturity (1.493 and 0.960), primary branches (0.667 and 0.045), pod bearing length (1.153 and 0.394), number of pods per plant (0.661 and 0.463) and 100 seed weight (0.352 and 0.426) had the highest positive direct effect on grain yield both at genotypic and phenotypic level. For maximizing the grain yield per plant emphasis should be given in selection of such characters for further improvement in pigeonpea.

The initial growth of turmeric is rather slow and takes about 4-5 months to cover the inter space. Therefore, the available space between the rows of turmeric could be effectively utilized by growing short duration crops like, vegetables, cereals etc. Hence, it is worthwhile to explore the possibilities of growing compatible crops with turmeric. With this background the experiment on effect of intercrops on growth and yield of turmeric was conducted at Agricultural Research Station, Bhavanisagar. Among the different intercrops, turmeric with cowpea recorded the maximum fresh rhizome yield per hectare (30.78 t ha-1) while turmeric + bhendi registered the maximum B:C ratio (2.68:1). Monocropping of turmeric recorded the lowest B:C ratio (1.67:1) among all the treatments.

Lentil (Lens culinaris) is an important winter season annual legume crop known for its highly valued seed in human and animal nutrition owing to its high lysine and tryptophan content. Shortage of water during the crop growth period has become the major impediment for cultivation of pulses in rice fallow in particular. Under such conditions, the application of hydrogel can be a potential alternative to improve photosynthetic efficiency, assimilate partitioning, and increase growth and yield. A field experiment was conducted from November to February during 2015–16 to 2017–18 on clay loam soil that was medium in fertility and acidic in reaction (pH 5.4) at Central Agricultural University, Imphal, Manipur. The experiment was laid out in split plot design with three replications. There were three hydrogel levels in total in the main plot and foliar nutrition with five different nutrient sprays in sub-plots, together comprising 15 treatment combinations. The data pooled over three years, 2015–2018, revealed that application of hydrogel at 5 kg/ha before sowing recorded a significantly greater number of pods per plant (38.0) and seed yield (1032.1 kg/ha) over the control. Foliar application of nutrients over flower initiation and pod development had a positive effect on increasing the number of pods per plant eventually enhanced the seed yield of lentil. Foliar application of either 0.5% NPK or salicylic acid 75 ppm spray at flower initiation and pod development stages recorded significantly more pods per plant over other nutrient treatments. Further, the yield attributed improved because of elevated growth in plant. Significantly maximum seed yield (956 kg/ha) recorded in the NPK spray of 0.5% remained on par with salicylic acid 75 ppm (939 kg/ha) over the rest of the treatments.

Variations in growth and yield of three hyacinth bean genotypes collected from Sitakundu of Chittagong, were investigated at the Agricultural Research Station (ARS) of Bangladesh Agricultural Research Institute (BARI), Pahartali, Chittagong during November 2011 to March 2012, where BARI Seem-4 was used as standard control. The minimum number of days for pod formation (54 days) was recorded in BARI Seem-4, while the maximum was in DLP 002 (62 days). The highest number of pods (324) per plant was obtained from DLP 001 followed by DLP 003 (212.33) and the lowest (148.33) was obtained from BARI Seem-4. The maximum weight (12.61 g) of single pod was observed in DLP 003, which is close to that of DLP 002 (12.23 g). The minimum weight of single pod (7.08g) was however observed in DLP 001. Weight of 100-green seed (117.17 g) was maximum in DLP 002, while that of DLP 001 was the minimum (85.90 g).The maximum green seed (61.86 %) was found in DLP 003 and the minimum was in DLP 001 (47.89 %). DLP 003 produced the highest pod yield (26.77 t/ha) which was followed by DLP 001 (22.94 t/ha), while BARI Seem-4 produced the lowest (17.43 t/ha), which is close to that of DLP 002 (19.57 t/ha).The Agriculturists 2014; 12(2) 01-05
