“…The cost involved under this treatment was comparatively lower than its additional income, which led to more returns under this treatment. Shilpa and Wali (2018), Kumawat et al (2020b) and Shirzad et al (2020) also reported the similar results.…”

A field study was carried out during the summer seasons of 2019 and 2020 at research farm of Agriculture University, Kota, Rajasthan, to study the effect of NP fertilization and stress mitigating chemicals on productivity and profitability of summer cowpea (Vigna unguiculata L.) and baby corn (Zea mays L.) intercropping system. The experiment was conducted in a split-split plot design with 5 intercropping systems [sole cowpea, sole baby corn, cowpea + baby corn (2: 1), (3: 1) and (4: 1)] in main plot; 3 fertility levels (100, 125 and 150% RDF) in sub-plot and 2 stress-mitigating chemicals (0.5% CaCl2 and 1.0% KNO3 at flowering and pod development stage of cowpea) in sub-subplot, replicated 4 times. Intercropping in 2:1 row ratio of cowpea and baby corn significantly increased the cowpea equivalent-yield, monetary advantage index, land equivalent ratio and economics of intercropping system while the yield of cowpea and baby corn was significantly higher under their sole crops. In sub-plots cowpea-equivalent yield, land-equivalent ratio, monetary advantage index, profitability, seed and cob yield of cowpea, and baby corn were higher with the fertility level of 150% over lower levels. Our results further indicated that 0.5% of CaCl2 significantly enhanced the cowpea-equivalent yield, monetary advantage index and economics of intercropping system and yield of cowpea and baby corn over 1% KNO3. Cowpea should be intercropped as 2:1 row ratio with fertilization of 150% RDF and foliar application of CaCl2 @0.5% at flowering and pod development stage of cowpea is recommended to achieve significantly higher productivity and profitability.

“…A positive and linear relationship between seed and biological yields of Indian mustard crop with heat-use efficiency was observed with 99 and 97% variability respectively. Shirzad et al, (2020), also reported a highly significant relationship between seed yield and HUE in wheat crop, For maximizing yield of 'Giriraj' Indian mustard, the crop may be sown by mid-October, i.e. 15 October, with crop geometry of 30 cm × 10 cm or 30 cm × 20 cm for maximum utilization of photo-thermal energy, increased photosynthetic activity which ultimately leads to efficient translocation of photosynthates to the sink and higher seed yields in Indian mustard crop in Jammu region.…”

A field experiment was conducted at the research farm of Sher-e-Kashmir University of Agricultural Sciences and Technology of Jammu, Jammu and Kashmir during the winter (rabi) season of 2014–15 and 2015–16, to study the effect of different dates of sowing and planting geometries on photo-thermal energy utilization and productivity of Indian mustard [Brassica juncea (L.) Czernj.] var. ‘Giriraj’. Results revealed that the crop sown on 15 October showed significant increase in yield attributes, viz. siliquae/plant (276.5), seeds/siliqua (17.2), test weight (3.54) and seed yield (1.31 t/ha) besides concomitant increase in utilization of thermal energy envisaged through accumulated growing degree-days (1671.2 oC/day), helio-thermal units (9,336.6 oC/day/hr) and photo-thermal units (17,859.7 oC/day/hr) as well as heat-use efficiency (HUE) of seed (0.783 kg/ha/oC/day) and biological yield (3.35 kg/ha/oC/day) as compared to the other dates of sowing. Seed yield of Indian mustard declined progressively with advancement in sowing beyond 15 October. However, among the different planting geometries, the maximum average seed yield (1.14 t/ha) was observed at planting geometry of 30 cm × 10 cm, being at par with 30 cm × 20 cm spacing but significantly higher than the other planting geometries to the tune of 11.1, 17.2 and 23.7% over the spacings 30 cm × 30 cm, 45 cm × 15 cm and 45 cm × 30 cm, respectively. The heat-use efficiency of seed and biological yield was found higher in earlier-sown Indian mustard and decreased progressively with delayed sowing.

Farm of Afghanistan National Agricultural Sciences and Technology University (ANASTU), Kandahar, Afghanistan to find out most suitable groundnut variety and their phosphorus levels in the study region. The treatments combination was of two groundnut varieties (Kormaki and Paparri) and four levels of phosphorus as P2O5 (P0= 0 kg P2O5 ha-1, P1=40 kg P2O5 ha-1, P2= 60 kg P2O5 ha-1 and P3= 80 kg P2O5 ha-1), were tested in a split plot design. Result revealed that Paparri variety produced significantly higher growth attributes (plant height, dry matter accumulation and number of main branches plant-1) and yield attributes (number of pods plant-1, pods dry weight plant-1, 100 kernel weight and shelling percentage) over Kormaki variety. Likwise, paparri variety produced significantly higher pods yield, kernel yield, haulm yield and biological yield over kormaki variety. In the like manner, significantly higher gross return, net return and benefit cost ratio was recorded from Paparri variety, whereas residual nitrogen was found significantly higher in kormaki variety. Among phosphorus levels, 60 kg P2O5 ha-1 recorded higher values for growth parameters, yield attributes viz. number of pods plant-1, pods weight plant-1, 100 kernel weight and shelling percentage, and yields (including pods yield, kernel yield, haulm yield and biological yield).
