“…The cost of trellis system is worked out to be Rs. 49000/-($760) per ha (Lal et al, 2016). Delayed flowering and fruiting habit and long duration of yard long bean do not allow them to fit in proper rice-wheat cropping system.…”

Sixty-six bush type advance breeding lines of vegetable cowpea developed at ICAR -Indian Institute of Vegetable Research (ICAR-IIVR), Varanasi were evaluated for different horticultural traits for genetic variability, character association, causeeffect analysis and genetic diversity among the genotypes through D 2 statistics. High values of genotypic and phenotypic coefficient of variations, heritability (h 2 B) and genetic advance were recorded for pod yield per plant, number of peduncles and pods per plant, peduncle length, number of primary branches per plant, pod length, pod weight and number of seeds per pod. Pod yield per plant showed strong positive correlation with number of peduncles and pods per plant, pod weight, pod length, number of seeds per pod and number of primary branches per plant, while negative correlation with days to 50% flowering at genotypic and phenotypic levels. The maximum direct positive effect on pod yield per plant was found contributed by number of pods per plant followed by pod weight. Based on degree of divergence the genotypes get grouped into seventeen clusters. The top three characters which contributed most towards the genetic divergence were number of peduncles per plant, peduncle length and pod length. The genotypes of cluster VII showed maximum genetic divergence with genotypes of cluster VIII. Further, cluster VII had the high yielding genotypes, while cluster XVII had early flowering genotypes. Thus, crossing between genotypes of these groups may result in high yielding early genotypes.

“…Early flowering (40-45 days after sowing) and early picking of green pods (50-55 days after sowing) had short duration of the crop (70-75 days) which could be grown in between the kharif -rabi i.e. rice-wheat cropping system suitable for growing in both springsummer and rainy seasons (Lal et al 2016). Pods are about 30-35 cm long, dark green, soft, fleshy and free from parchment.…”

Vegetable cowpea variety “Kashi Kanchan” is an improved variety released by ICAR-Indian Institute of Vegetable Research (IIVR) in 2007. This variety is being widely adopted and cultivated by the farmers in different parts of the country. The economic impact of the variety Kashi Kanchan is analyzed using Economic Surplus Model (ESM). The results showed that, there was Rs. 111.21 crore of total economic surplus generated of which Rs. 43.81 crore was producer surplus and Rs. 67.40 crore was the consumer surplus. The net profit earned by cultivation of Kashi Kanchan variety was Rs. 36406/ac higher than that of local variety grown during rainy season and Rs. 84942 per ac during summer season. The BC ratio was 3.26 for summer crop and 3.04 for winter crop of Kashi Kanchan and 1.43 for the local variety. The total estimated area covered under the cultivation of Kashi Kanchan variety was 90314.8 ha from 2007-08 to 2019-20 covering a total of 443 districts in 29 states and 2 union territories in the country.

Aquaponics is one of the most effective, water-efficient, self-fertilizing, and eco-friendly technologies for organic food production. In this system, plant nutrients instigate from the fish feed and fish waste. The objective of the current study was to assess and compare the plant growth and fish production in different fish stocking densities in aquaponics. Four different densities were tested for the study, such as 2.94 (T1), 3.92 (T2), 4.90 (T3), and 5.88 (T4) kg m -3 tilapia with an initial length of 16.8±0.17 cm and a weight of 72.6±5.14 g, respectively. The tilapia were fed with commercial floating feed twice daily at 3% body weight. Sampling of fish and plant growth parameters were carried out fortnightly, whereas, water quality parameters such as temperature, dissolved oxygen, and pH were measured weekly, and electrical conductivity (EC), total dissolved solids (TDS), ammonia, nitrite, and nitrate were measured fortnightly. The data interpretation showed that pH, ammonia, nitrite, EC, and TDS were significantly increased with the increasing fish densities. On the other hand, except Zn, Fe and Mn, all other nutrients of the fish tanks were significantly increased with the fish densities in the treatments. The first flower and pod appearance were observed in T3 at 39.33±4.03 and 44.06±4.09 days, respectively those were significantly the lowest with the fish density of 4.90 kg m -3. The highest and the lowest cowpea production were 4.61±0.88 and 2.50±0.71 kg m -2 in T3 and T4, respectively. However, the highest fish production was 14.76±0.71 kg m -3 in T4, although T3 performed better in the case of other components, where most of the fish growth parameters were statistically similar among the treatments. Moreover, almost all the proximate compositions of cowpea and fish were statistically similar except that the moisture content in the tilapia and ash content in cowpea were significantly different. The study showed that the stocking density of the tilapia of 4.90 kg m -3 resulted in higher production of cowpea by maintaining good water quality for the plant compared to the other stocking densities.
