The experiment was carried out to study the performance of garden pea genotypes for growth, yield and quality during rabi season (November to april) of 2017–18 and 2018–19 with the help of split plot design through three number of replications. The results of the study revealed that, early flowering, flowering at early node and days to first harvest was earlier by 2.32, 2.90 and 0.89 days, respectively in rainfed conditions. Yield parameters like individual plant yield, number of pods plant-1, individual pod weight and total fresh yield were significantly reduced by water stress condition. Number of nodules plant-1 (7.93) and nodule dry weight (97.01 g) decreased in rainfed conditions, whereas root length (22.33 cm) was higher in rainfed condition. Considering yield, benefit cost ratio and moisture stress tolerance of garden pea genotypes, TSS content of fresh seeds was higher in rainfed conditions. Quality parameters such as protein content and shelling percentage were higher in irrigated conditions. Ascorbic acid content remained unchanged under both growing conditions. The varieties such as Arka Apoorva, Arka Priya, Goldie and GS-10 may be selected for cultivation under both irrigated and rainfed conditions. On the basis of per se performance and drought tolerant indices Arka Apoorva, Arka Priya and Jindal-10 may be selected as suitable for growing under moisture stress condition in terai agro-ecological condition of West Bengal.

Thirty days grown seedlings of eight genotypes of groundnut viz. RHRG-6083, TAG-24, TG-60(LC), Karad-4-11, SB-XI, RHRG-6097, RHRG-6021, and RHRG-6055 were subjected to moisture stress by withholding irrigation for 15 days in pot culture experiment in order to evaluate its effect of on RWC , proline accumulation, soluble proteins, chlorophyll content and activities of superoxide dismutase (SOD), peroxidase (POX), glutathione reductase (GR) and lipid peroxidation (MDA).The levels of proline, soluble protein and the activity of all four antioxidative enzymes were found to be increased with MDA content in all genotypes of groundnut during water stress, however the chlorophyll and RWC content were found to be decreased. This study revealed that under water stress condition SB-XI, TAG-24 and RHRG-6021 showed higher increase of proline content and activities of antioxidative enzymes with lower reduction in RWC and chlorophyll. These three genotypes are stable during stress and seems to be promising for drought tolerance.

An investigation was taken up on eight years old seedling trees of jackfruit, planted at 10 x 10 m spacing at the Horticultural Research Station, Mondouri (Nadia, West Bengal) of the Bidhan Chandra Krishi Viswavidyalaya with a view to know the effect of different organic manures and inorganic nutrients (N, P and K) on production, fruit quality, soil heath and foliar NPK status. Results from the three consecutive years of investigation, it was revealed that highest dose of NPK (N 500 P300 K300 g/tree/year) resulted in highest yield (76.3 kg / tree) but gave lower BCR (benefit cost ratio) of 1.13 while its lowest dose (N200P100 K100 g/tree/year) gave higher BCR of 2.00. Among the organic manures, vermicompost at 4.00 kg/tree/year produced second higher yield (56.3 kg/tree) with best quality fruits and this treatment resulted in highest BCR of 2.17. Soil NPK status and pH improved under different treatments as compared to respective initial values. Foliar NPK values were differed among the treatments although it could not be correlated to the fruit yield.

Abstract The experimental material for the present study comprised of 28 inbred lines (including two checks) which were developed by mutation and hybridization among the lines from AICRP trials MARS, UAS, Dharwad and on the basis of SPAD readings and stay green nature, they were considered as drought tolerant lines. These lines were used for the present experiment and were evaluated under both normal and moisture stress condition in rain out shelter to study their root characteristics. Among 28 inbreds evaluated, eight inbred lines i.e. DSR-13, DSR-19, DSR-23, DSR-24, DSR-37, DSR-66, DSR-107 and DSR-132 were identified as drought tolerant nature which exhibited least reduction in their yield under moisture stress condition. Simultaneously hybridization programme was also initiated during summer 2018 using these 28 inbred lines as testers (males) and 5 CMS lines as female lines in Line × Tester fashion. Among 140 hybrids developed, only 40 F1 hybrid combinations were further analyzed for heterosis and combining ability studies along with four checks RHA 6D-1, RHA 95C-1, KBSH-53 and Cauvery Champ. Most of the hybrid combinations showed significant negative heterosis for flowering indicating earliness, and also all the combinations showed a positive heterosis for plant height indicating tallness dominant over dwarf checks. The combinations CMS 7-1-1 A × DSR-37 (624 kg/ha), CMS-853A × DSR-19 (624 kg/ha), and CMS-853A × DSR-23 (619 kg/ha) exhibited significant maximum heterosis for seed yield (kg ha−1) over the checks KBSH-53 (496.50 kg/ha) and Cauvery Champ (486.50 kg/ha) showing maximum seed yield per hectare.

The objective of this study was to evaluate the competitiveness of two cultivars of upland rice drought-tolerant, cultured in coexistence with weed S. verticillata, under conditions of absence and presence of water stress. The experiment was conducted in a greenhouse at the Experimental Station of the Universidade Federal de Tocantins, Gurupi-TO Campus. The experimental design was completely randomized in a factorial 2 x 2 x 4 with four replications. The treatments consisted of two rice cultivars under two water conditions and four densities. At 57 days after emergence, were evaluated in rice cultivars and weed S. verticillata leaf area, dry weight of roots and shoots and total concentration and depth of roots. Was also evaluated in rice cultivars, plant height and number of tillers. Water stress caused a reduction in leaf area, the concentration of roots and vegetative components of dry matter (APDM, and MSR MST) of rice cultivars and Jatoba Catetão and weed S. verticillata. The competition established by the presence of the weed provided reduction of all vegetative components (MSPA, and MSR MST) of cultivars and Jatoba Catetão. It also decreased the number of tillers, the concentration of roots and leaf area. At the highest level of weed competition with rice cultivars, a greater decrease in vegetative components and leaf area of culture, regardless of water conditions.

Aim: Identification of high breeding value donor lines harbouring tolerance to moisture stress from diversity stock of 443 genotypes of Brassica juncea. Methodology: Germplasm stock of 443 Indian mustard (Brassica juncea L.) genotypes, comprising introgression lines, land races, old cultivars and advance breeding lines, were evaluated under two environments viz., irrigated and rainfed conditions to check the variability for yield and related traits. Statistical software META-Rver 6.0 (Multi Environment Trial Analysis using R) was used for computation of Best Linear Unbiased Predictions, Analysis of Variance (ANOVA), Genetic Correlations and Heritability. Drought susceptibility index and per cent seed yield reduction under rainfed conditions were used as indicators to determine moisture stress tolerance in genotypes. Results: The variability for moisture stress tolerance has been unravelled in a diverse genetic stock of Brassica juncea under two environments: irrigated and rainfed. For high prediction accuracy, the ranking of genotypes was done based on Best Linear Unbiased Predictions for seed yield and its component traits. PBR-378, RGN-329, RB-73, RB-50 and PBR-422 and Giriraj were identified as moisture stress tolerant genotypes. One land race Sahib 36 and three introgression lines viz., MCP 12-211, PTJ-3-69 and MSC-3 have also been identified as potential genetic resources for moisture stress tolerance. Principal component analysis based on biplots depicted specific distribution of variables for each environment. Interpretation: This study led to the identification of potential donors for moisture stress tolerance with high predictive accuracy. Low drought susceptibility index and high breeding value in a land race and three introgression lines derived from Erucastrum cardaminoides, B. tournefortii and B. carinata emphasized their utilization as potential genetic resources to breed for moisture stress tolerance in B. juncea.

Chickpea is an important pulse crop grown during rabi season in black soil areas of Dharmapuri District. Among the various biotic and abiotic factors, the drought stress and fusarium wilt disease incidence are the major problems that reduces the chickpea yield to a greater extent. To overcome the above problems, the varieties viz., JAKI 9218 and GBM 2 were studied in comparison with farmers practice i.e., CO 4 for identification of suitable drought and disease tolerant high yielding variety for prevailing rainfed condition. The results revealed that JAKI 9218 and GBM 2 were found promising under rainfed condition and recorded the grain yield of 1008 and 933 kg/ha as compared to 808 kg/ha in CO 4. The variety JAKI 9218 proved to be superior with a yield increase of 24.7 per cent over CO 4 and 8.04 per cent over GBM 2. The pod borer and fusarium wilt disease incidence were lower in the variety JAKI 9218. The highest net income of Rs. 22158 /- and benefit cost ratio of 2.16 was realized in JAKI 9218 and the lowest net income of Rs. 13958 /- and benefit cost ratio of 1.77 was realized in farmers practice i.e., CO 4. It is concluded from the study that the chickpea variety JAKI 9218 can be recommended for large scale cultivation under rainfed condition of Dharmapuri district for realizing higher return by the farmers.
