All agricultural operations require energy in one form or the other viz., manpower , fuel (diesel), irrigation, machinery, inorganic fertilizers, and agro-chemicals (Kumar et al., 2021). Energy consumption in agriculture has intensified in recent years due to increased production of food grains to feed the burgeoning population. Thus, intensive energy use through adoption of an intensive management package of practices and growing of high yield potential cultivars has threatened the sustainability of agriculture, environment, and public health. In order to meet the growing demand of the increasing population and to lower down the environmental hazards, declining energy use and enhancing the energy use efficiency are the only possible solutions that are vital for sustainable agriculture. Mungbean also known as greengram [Vigna radiata (L.) Wilczek] is a versatile pulse crop. Being rich in quality proteins, minerals, vitamins etc., this crop is an inseparable ingredient in the diet of the Indian population. Its proteins are considered highly

The field experiment comprising eight treatments viz., control and seven growth regulation treatments (detopping, MC (mepiquat chloride) @ 200, 250 and 300 ppm applied once at 35 days after sowing (DAS) and twice at 35 and 45 DAS was conducted in a randomized complete block design (RCBD) with four replications. The grain yield obtained with foliar application of MC @ 250 ppm at 35 and 45 DAS (10.05 q/ha) was significantly higher than control (6.70 q/ha). Various growth parameters and yield attributes (dry matter accumulation and number of pods per plant) were also significantly higher with MC @ 250 ppm (35 and 45 DAS) as compared to control. Detopping resulted in highest leaf area index (LAI), whereas all other growth regulation treatments were signifi...

The experiment was laid out in a randomized complete block design with four replications comprising twelve treatments, viz. control, thidiazuron 100, 150 and 200 g/ha, ethrel 1.0 and 1.5 l/ha applied at 40 or 60 BOP and gramoxone (paraquat) 1.0 l/ha applied after first picking. Defoliation with ethrel 1.5 l/ha at 60 BOP resulted in higher number of picked bolls/plant and BOP when compared with control. However, maximum seed cotton yield was obtained with ethrel at 1.0 l/ha (2.27 and 1.96 t/ha) and it was followed by thidiazuron 100 g/ha (2.21 and 1.92 t/ha) applied at 60 BOP. Gramoxone (paraquat) application at 1.0 l/ha after first picking failed to exert any significant influence on seed cotton yield and yield contributing characters. The B:C ratio of thidiazuron 100 g/ha at 6...

The experiment was laid out in split-plot design, with three methods of crop establishment i. e. conventional, bed planting and zero-till in main plots and three irrigation schedules viz. 1.25, 1.00, and 0.75 IW:CPE in sub plots with four replications. The grain yield of wheat did not vary significantly with different methods of crop establishment. However, zero-till sowing was found to be more remunerative in terms of net returns, benefit: cost and specific energy over conventional and bed planting. Among the irrigation schedules maximum grain yield (48.2 q/ha) was obtained when irrigation applied at 1.25 IW: CPE, which was statistically at par with 1.0 IW: CPE (46.8 q/ha), but both were significantly better than irrigation applied at 0.75 IW: CPE (43.7 q/ha). Similar trend was observed for net returns ...

Fateh Garh Sahib) for three years under irrigated conditions for productivity enhancement through integrated nutrient and other agronomic interventions. There were twelve treatments comprising different levels of N, P, K, FYM and agronomic management practices. The results revealed that soybean significantly responded to the application of N, P, K and FYM. Maximum yield was recorded in the treatment where FYM was applied with NPK and resulted in an increase of 10.8 per cent over NPK alone. Application of additional 30 kg N ha-1 at pre-flowering or at pod initiation did not significantly enhance the yield over the basal dose of NP applied at sowing. Application of 4 tonnes wheat straw mulch + 30 kg N +60 kg P2O5 and 30 kg N + 60 kg P2O5 ha-1 showed similar effect on seed yield of soybean. No statistical difference in soybean yield was observed in the con...

A two year investigation was conducted at Punjab Agricultural University, Ludhiana, during kharif seasons of 2014 and 2015. The experiment was laid-out in randomized complete block design (RCBD) with eight treatments viz. control, detopping (removal of 4-5 cm apical portion of main stem) at 50-55 days after sowing (DAS), mepiquat chloride @ 200 ppm (50-55 DAS), mepiquat chloride @ 200 ppm (50-55 + 65-70 DAS), mepiquat chloride 250 ppm (50-55 DAS), mepiquat chloride @ 250 ppm (50-55 + 65-70 DAS), mepiquat chloride @ 300 ppm (50-55 DAS) and mepiquat chloride @ 300 ppm (50-55 + 65-70 DAS) with four replications. Detopping had a non-significant effect on leaf area index, SPAD value, PAR interception, abscission of reproductive parts, seeds per pod, 100-seed weight, pod length and stover yield of soybean. It significantly decreased plant height, increas...

The results revealed that application of FYM with NP or NPK improved the yield of soybean over NP or NPK alone treatment. Integrated use of FYM with NPK increased the yield of soybean by 5.9 per cent over NPK alone. Additional application of 30 kg N ha-1 at pre-flowering or at pod initiation did not increase the yield over the basal dose of NP applied at sowing. Use of 4 tonnes wheat straw mulch + 30 kg N, 60 kg P2O5 and 30 kg N, 60 kg P2O5 ha-1 showed similar effect on seed yield of soybean. Conventional flat sowing and bed sowing of soybean were equally effective in influencing the soybean yield. Pre-emergence application of pendimethalin at 1.5 l ha -1 along with one hand weeding at 40 days after sowing (DAS) and two hand weeding at 20 and 40 DAS were equally effective ...

The experiment was laid out in split plot design with four replications. The main plots comprised three dates of sowing i. e. October 10, October 25 and November 10. The growth regulation practices viz., detopping, mepiquat chloride (MC) @ 250 ppm and MC @ 500 ppm applied as foliar spray at 40 and 70 days after sowing (DAS) along with unsprayed control were kept in sub-plots. November 10 sown crop produced significantly higher dry matter (39.5 g/plant), more number of primary (5.3) and secondary (17.3) branches, flowers (88.6) and pods (55) per plant, and grain yield (21.1 q/ha) than October 10 and October 25 sown crop. MC @ 500 ppm applied at 70 DAS produced significantly higher grain yield (18.13 q/ha) which was statistically at par with MC @ 500 ppm (17.47 q/ha) applied at 40 DAS. Detopping failed to influence the seed yield signi...

Fiori & Paol] sequence under different methods of crop establishment during 2005–06 and 2006–07. The treatments included combinations of two crop establishment methods of basmati rice (direct seeded and transplanted) and three seeding techniques of succeeding wheat (conventional, bed planting and zero tillage). Productivity of basmati rice-wheat sequence was significantly higher with transplanted basmati rice (TPBR) than direct seeded basmati rice (DSBR) irrespective of seeding technique of succeeding wheat. However, crop establishment methods of wheat did not show any significant impact on total productivity of basmati rice-wheat sequence during both the years. Total water use was 9.5 and 8.2 per cent higher in TPBR-wheat sequence than DSBR-wheat sequence during 2005–06 and 2006–07, respectively. In this sequence the hi...

The experiment was laid out in split plot design, keeping combinations of three dates of sowing (Oct. 30, Nov. 15 and Nov. 30) and two cultivars (RLC 1 and RLM 619) in main plots and four irrigation schedules (40, 60, 80 CPE and two irrigations at four weeks after sowing and at flowering) in sub-plots with three replications. Raya sown on October 30 recorded significantly higher primary and secondary branches than November 15 and November 30 sown crops. The yield attributes, seed and oil yield were also significantly higher in October 30 sown crop than November 15 and November 30. Similar trends were observed for water use and water use efficiency (WUE). Both the cultivars did not differ significantly for yield attributes and seed yield. However, cultivar RLM 619 recorded significantly higher oil content and oil ...

This problem needs to be addressed to obtain optimal yields. Abscission can be regulated by manipulation of the environment or by application of chemicals. The factors, like moderate temperature, moderate water supply, normal light intensities, adequate mineral nutrients, freedom from diseases and insects tend to prevent or delay abscission. Growth retardants, like mepiquat chloride (MC) and cycocel (CCC) reduce internode length, thereby, reducing plant height and stimulating the translocation of photosynthates towards sink. MC 50 ppm sprayed at 90 DAS (days after sowing) resulted in significantly higher yield (11.9 %) over control. Late opening of mature bolls is also one of the major factors limiting crop productivity. Cotton hybrids usually attain excessive vegetative growth and thick crop canopy with poor boll opening especially when crop encounters low temperatu...

Since photosynthesis is one of the principal components in determining yield. So, the objective of this study was to determine how manipulations of ratio of photosynthetic source to reproductive sink affect cotton lint yield and yield components. Field studies were conducted in 2011 and 2012 on a loamy sand soil of Ludhiana, India with four source to sink manipulations; [P1 (All fruiting forms were removed except first position), P2 (All fruiting forms were removed except second position), P1P2 (All fruiting forms were removed except first and second position) and untreated control] imposed on three genotypes (MRC 7017, MRC 7031 and RCH 314) in split plot design with four replications. The results revealed that the P1P2 yielded 23.2 and 22.02 per cent higher seed cotton yield over P1 and 55.5 and 52.9 per cent over P2 during 2011 and 2012, respectively....
