Economic Analysis of Cucumber-Based Crop Rotations Under Protected Structures in Haryana, India
The present study was conducted in Haryana state to find out the economics of crop rotation in the protected structures. In the study area, four cucumber-based crop rotations were found i.e. cucumber + cucumber (R1), cucumber + capsicum (R2), cucumber + tomato (R3), cucumber + lilium (R4). Sonepat, Karnal, and Hisar districts were purposively selected because of the predominance of protected structures. The results obtained in this study indicated that the R4 cropping rotation (₹4838447) has higher cost of cultivation followed by R2 (₹1765041), R3 (₹1760968) and R1 (₹1574530). Gross returns were higher in case of R4 cropping rotation (₹6942780) is a higher cost of cultivation followed by R3 (₹2261224), R2 (₹2215500) and R1 (₹2126250). Net returns were highest in R4 (₹2137185) followed by R1 (₹511720), R3 (₹500255) and R2 rotations (₹450459). The present study also revealed that maximum respondents were adopting R1 crop rotation because of the lesser cost of cultivation and higher net returns.
Screening of Various Genotypes of Okra [Abelmoschus esculentus (L.) Moench] Against Major Insect Pests
Out of 10 varieties of okra, Abelmoschus esculentus (L.) Moench screened against the sucking insect pests [leaf hopper, Amrasca biguttula biguttula (Ishida) whitefly, Bemisia tabaci (Genn.)] and fruit and shoot borer (Erias spp), none of the variety was found completely free from their infestation, although they differed significantly in their degree of damage and pest number to harbor. During both the kharif seasons, 2019 and 2020, Punjab Padmini reported as the least susceptible variety against both leafhopper (6.26 nymphs/plant) and whitefly (9.32 adults/plant) whereas, lowest fruit and shoot borer infestation was observed on Hisar Naveen (Percent shoot damage- 8.51 Percent fruit damage on number basis- 29.07 Percent fruit damage on weight basis- 29.93). Meanwhile, Arka Nikhita F1 was noted as the most susceptible variety among all the screened varieties against all three major insect pests (Leafhopper- 9.80 nymphs/plant; Whitefly- 15.29 adults/plant; Percent shoot damage by Earias spp.- 12.14 Percent fruit damage by Earias spp. on number basis- 37.18 Percent fruit damage by Earias spp.on weight basis-38.02) investigated during the study period. However, rest of the varieties viz., Hisar Unnat, Varsha Uphar, Punjab Suhawani, Arka Anamika, Punjab-8, Pusa Sawani, Parbhani Kranti were concluded as moderately susceptible varieties.
Closing Yield Gaps Through Agronomical And Socio-Economical Factors
Yield gap analysis of individual crops in a cropping system has been done to explore the opportunities for increasing crop production which may provide important information to the policy makers for augmenting food security. In this context, study has been undertaken in Terai Zone of India, specifically West Bengal. The cropping system predominantly in the area is Kharif Paddy-Potato-Jute. We used econometric models Multiple Regression Analysis, for identified the factor which is cause to yield gaps. The result shows that Yield gaps have been found for all crops as well as cropping pattern of farmers in various levels. Regression analysis reveals that various factors like participate family member in farming, family head of education, age of head, farm holding, contact with social office, manures, farm distance etc. remain the most significant ( p< 0.01; p<0.05; p<0.1 ) to influence the yield gap. This led to the conclusion that the yield gap could be deeply reduced by controlling local agronomic management and improving socioeconomic factors.
Impact of Weed Management Strategies Evaluated through Various Agronomic Indices in Direct Seeded Basmati Rice Preceded by Wheat in Sequence
A field experiment was conducted consecutively for two years in the Shivalik foot hill plains of Jammu and Kashmir on weed dynamics in direct seeded basmati rice that was preceded by wheat. In this study, the impact of different weed management strategies on crop productivity was assessed. The measures adopted to control weeds resulted in the notable enhancement in crop yields. In wheat, the combined application of Isoproturon @1.0 kg/ha + 2,4-D @ 0.500 L/ha as post emergence (30 DAS) was the most effective weed management approach that gave significant control of weeds which in turn increased crop yields. Weed density (no. of weeds/m2) and weed dry weight (g/m2) were recorded minimum with treatments Isoproturon @ 1.0 kg/ha + 2,4- D @ 0.500 L/ha which was statistically at par with mechanical weeding at 30 and 60 DAS. The same treatment produced significantly superior grain yield in comparison to all treatments under study. In the succeeding crop of direct seeded (DS) basmati rice, sequential application of Pendimethalin @ 1.0 kg/ha (PE) fb Bipyribac @ 0.030 kg/ha as post- emergence (at 30 DAS) turned out to be the most superior treatment that resulted in the highest suppression of weeds consequently maximum crop grain yields were recorded under the same treatment. Efficacy of different weed control interventions in both the crops were also reflected through various Agronomic Efficiency Indices used in the present investigation.
Effect of different organic farming packages on yield, biochemical properties and energy balance study under diversified cropping systems
Considering the importance of organic farming and growing demand for organically produced quality foods, field studies were conducted for 2 years (2015-16 to 2016-17) on clay loam soil at the IFSRP, Rahuri, to study the effect of different organic farming packages on yield, biochemical properties and energy balance study under diversified cropping system. The highest total system productivity, biochemical properties and energy balance were obtained under onion - chickpea cropping system followed by onion – rabi sorghum with the application of 50 % N through FYM + 50 % N through vermicompost for kharif season crops followed by a direct effect of 100 % N through organic i.e. 50 % N through FYM + 50 % N through vermicompost to rabi season crops than rest of the treatments.
