SUMMARY

Eighty sorghum genotypes possessing forage and sweet sorghum characters along with standard resistant, susceptible and local checks were screened for resistance to major insect pests including sorghum shoot fly and spotted stem borer under natural field conditions at Hisar (Haryana), India during rainy season (kharif) – 2019. Per cent deadhearts caused by shoot fly and stem borer were recorded at 28 and 45 days after emergence, respectively, under natural field conditions. Fifteen genotypes namely, RBSV 36, SFRM 4, SFRM-6, SFRM-8, SFRM-9, SPH 1881, SPH 1933, SPV 2669, CSH 24MF, SSG 59-3, CSV 33MF, SPV 2712, SPV 2604, SPV 2692 and CSV 19SS performed better by registering less percentage of deadhearts caused by Atherigona soccata and Chilo partellus.

SUMMARY

A field experiment was conducted during 2018 to study the growth and production of fodder cowpea (var. RC-19) under different spacing’s, i.e. 3 × 3 m, 4 × 3 m, 5 × 3 m, 6 × 3 m, 7 × 3 m and 8 × 3 m of two and half year old poplar-based agroforestry system. The maximum plant population (20.17/m2) was recorded in 8×3 m spacing followed by 7×3 m, 6×3 m, 5×3 m, 4×3 m and least under 3×3 m at 15 DAS. A similar trend of plant height and leaf area index of cowpea was observed after 30, 45, 60 and 75 DAS as it follows the increasing trend with increase in spacing. Among the different spacing’s of poplar, the fodder yield of cowpea was recorded maximum (8.95 t/ha) under 8×3 m followed by 7×3 m (7.24 t/ha), 6×3 m (6.06 t/ha), 5×3 m (4.45 t/ha), 4×3 m (2.99 t/ha) and minimum (2.20 t/ha) under 3×3 m spacing. All the growth and yield attributes of cowpea were recorded lesser under different spacing’s of poplar as compared to the control (devoid of trees). The reduction in fodder yield under different spacing’s 3 × 3 m, 4 × 3 m, 5 × 3 m, 6 × 3 m, 7 × 3 m, 8 × 3 m of poplar was 81.71, 75.14, 63.00, 49.62, 39.81 and 25.60 per cent, respectively over control (sole cowpea), demonstrating that the cowpea is susceptible to shade. While maximum (2.03) benefit to cost ratio was observed under poplar + cowpea combination in closer plant geometry of 3×3 m due to more number of trees.

Key words:Agroforestry, cowpea, poplar, spacing, fodder yield

SUMMARY

Farmers’ participatory front line demonstrations on integrated crop management (ICM) practices and traditional method of sowing as farmers’ practice (FP) were conducted during kharif (2013-2015) under CCS, HAU, Krishi Vigyan Kendra, Fatehabad, Haryana. The study revealed that on an average 12.34 q/ha yield of cluster bean (var. HG 2-20) was recorded under ICM as compare to 9.65 q/ha in FP which was 27.9 per cent higher over that of the FP. The pooled value of extension gap, technology gap and technology index was to the tune of 2.68, 5.16 q/ha and 30 percent, respectively. The data on economic parameters reveals that a net return of Rs.10329 per ha was in ICM compare to Rs.1447 per ha in FP. The benefit-cost (B:C) ratio was figured 1:1.22 and 1:1.03 in ICM and FP, respectively. Further, increased in an effective Rs. 8882 per ha, suggesting its higher profitability and economic viability of the technology demonstrated.

Key words:Cluster bean, ICM, yield, gap analysis, economics and BC ratio

SUMMARY

In Haryana, sorghum is grown as fodder crop in 40.3 thousand hectare, and total production of sorghum is 21.3 thousand tones with average yield of 528 kg per hectare (DOA & FW, Haryana). The study was undertaken to identify the constraints faced by the farmers in sorghum cultivation. In Gurugram district, two blocks were selected and out of these two blocks, eight villages were selected randomly for the study (Four villages from each block). Thus, 120 sorghum growers were personally interviewed with the help of a well structured interview schedule. Main constraints faced by the farmers in adoption of the recommended package of practices of sorghum are described. For better interpretation and analysis, all the constraints faced by farmers were classified into three categories i.e. related to inputs, constraints related to marketing and constraints related to production. Weighted mean score and rank order were calculated to find out the highest constraints faced by the respondents. Input constraints clearly showed that high prices of agro-chemicals was the main constraints faced by the respondents followed by non-availability of inputs at proper time, lack of finance for purchase of inputs, high labour and non- availability of the quality seed was the least serious constraint faced by respondents related to the inputs. Among marketing constraints, lack of transport facilities and disposal of produce were the main constraints followed by lack of guidance for proper time and place of marketing was second more serious constraints, no support price of produce was the least or not so serious constraint related to marketing.

Key words:Production, constraints, forage sorghum, marketing, input, seed and pesticide

SUMMARY

The present experiment was conducted with a view to study the suitability and profitability aspects of different intercrops for mango orchard cv. Amrapali in order to get additional income. There were 7 different treatments viz., Mango + cowpea, Mango + soybean, Mango + cluster bean, Mango + pigeonpea, Mango + maize, Mango + black gram and control (clean cultivation) had taken. The fruit yield of mango with intercrops was higher. The highest number of fruits per plant, yield per plant and yield per hectare was found when companion intercropping system of soybean, followed by cowpea, and black gram. it was observed that the yield parameter of mango increases when intercrop with leguminous crops. Similarly, several physical characteristics like fruit diameter, length and fruit weight increase significantly and found highest when intercropped with Soybean. The chemical analysis of mango fruits revealed that the TSS, total sugar percentage and ascorbic acid found to increased non-significantly among the treatments and found higher when inter-cropped with soybean and titratable acid noticed higher in control. The highest annual returns obtain when mango inter-cropped with maize followed by cluster bean and cowpea.

Key words:Mango, Amrapali, intercrop and legumes
