Background: Being an efficient N- fixer, mungbean improve the soil fertility status and can thereby serve as a useful component in any viable cropping system in the country. PROM has to be a better source of phosphate application. Indian soils are deficient in organic carbon. Sulphur is mostly applied to oilseed and pulse crops found to benefit more than one crop in a sequence due to its significant residual response. Methods: The investigation was conducted during kharif season of 2019 comprising five levels of phosphorus sources (Control, 16 kg P2O5/ha through DAP, 16 kg P2O5/ha through PROM, 32 kg P2O5/ha through DAP and 32 kg P2O5/ha through PROM) and three levels of sulphur (Control, 15 and 30 kg/ha) making 15 treatment combinations replicated three times in factorial randomized block design. Result: Application of 32 kg P2O5/ha through PROM recorded significantly higher growth, yield attributes, yields as well as net returns ( 50440) with B:C ratio 2.93 as compared to 16 kg P2O5/ha through DAP, 16 kg P2O5/ha through PROM and 32 kg P2O5/ha through DAP. With regard to sulphur levels application of sulphur up to 30 kg/ha recorded significantly higher growth, yield attributes, yields as well net returns ( 46723) with B:C ratio 2.96 over control and 15 kg S/ha.

An experiment was conducted during Kharif, 2016 to investigate the influence of transplanting dates and nitrogen levels on productivity of transplanted fine rice. Experiment was laid out in factorial randomized block design with two transplanting dates (i.e. D1-15th and D2-30th July) as one factor and four levels of nitrogen (i.e. 0, 30, 60 and 90 kg N/ha) as second factor. Time of transplanting did not influence growth, yield attributes and yield. However, among different levels of nitrogen, significantly highest yield and yield attributes were recorded with 60 kg N/ha. Significantly highest straw yield was recorded with 90 kg N/ha. Rice transplanted on 15th July proved to be superior with respect to gross returns (Rs.70337.50/ha), net return (Rs.38259.28/ha) and B: C ratio (1.19) to that of 30th July transplanting. Whereas among nitrogen levels highest gross returns (Rs.79307.50/ha), net returns (Rs.52314.96) and B: C (1.94) ratio were obtained with application of 60 kg N/ha.

A field experiment was conducted to investigate the effectiveness of different herbicides for controlling wild onion (Asphodelus tenuifolius) in cumin (Cuminum cyminum L.) during the rabi seasons (2018–2019 and 2019–2020) at Agricultural Research Station, Agriculture University, Jodhpur, Rajasthan. The experiment comprised eight herbicidal weed management treatments for wild onion applied to cumin in a three-replication randomized block design. Among the herbicidal weed management treatments, early post-emergence (8 DAS) application of oxyfluorfen 200 g/ha resulted in the lowest weed density and dry matter of Asphodilus tenuifolius, with maximum weed (Asphodilus tenuifolius) control efficiency at 40 days after sowing (DAS) during both experimental years. Likewise, the highest total efficiency of weed control was recorded with the application of oxyfluorfen 200 g/ha at 8 DAS. Oxyflourfen 200 g/ha used early post emergence (8 DAS) reduced the weed index more effectively than the other herbicides. It also recorded the highest number of branches/plant, plant height, umbels/plant, umbellates/umbel, seeds/umbellates, and seed yield. However, application of oxyflourfen @ 200 g/ha 8 DAS–early POE and pendimethalin 38.7 CS 500 g/ha + oxyfluorfen @ 150 g/ha 8 DAS–early POE were statistically similar in terms of plant growth, yield, and yield attributes. The net returns (366.49 USD/ha in 2018–2019 and 175.72 USD/ha in 2019–2020) and B:C ratio (1.70 and 1.33 in 2018–2019 and 2019–2020, respectively) were also superior, with oxyfluorfen 200 g/ha applied early post emergence.

A field experiment was conducted during 2016-17 at AICRP on Integrated Farming Systems, Regional Sugarcane and Rice Research Station, Rudrur to diversify existing rice-rice cropping system with less water requiring crops under irrigated dry conditions for vertisols of Northern Telangana Zone. The experiment was laid out with twelve cropping systems as treatments in Randomized Block Design (RBD) with three replications. The twelve combinations of cropping systems tested during kharif and rabi seasons were rice – rice (check), maize + soybean (2:4) – tomato, maize + soybean (2:4) - rice, maize - sunflower + chickpea (2:4), maize - chickpea, Bt cotton + soybean (1:2) on broadbed – sesame + groundnut (2:4), Bt cotton - sesame + blackgram (2:4), soybean – wheat, soybean – sunflower + chickpea (2:4), turmeric – sesame, turmeric + soybean (1:2) on flat bed – bajra and turmeric + soybean (1:2) on broadbed – sesame + blackgram (2:4). On system basis, significantly higher productivity in terms of rice equivalent yield (REY) of 23830 kg ha-1 was recorded with turmeric+soybean (1:2) BBF– sesame+blackgram (2:4) turmeric – sesame cropping sequence. However it was on par with turmeric – sesame and turmeric + soybean (1:2) on flat bed – bajra crop sequence with productivity of 23332 kg ha-1 and 21389 kg ha-1 respectively. Lower productivity was recorded with rice-rice cropping system (10725 kg ha-1). Significantly higher system net returns were recorded with Bt. cotton – sesame + black gram (2:4) on BBF (Rs222838 ha-1) closely followed by Bt Cotton + Soybean (1:2) (BBF) - Sesamum + Groundnut (2:4) (Rs221160 ha-1) and Maize+soybean (2:4)–tomato (Rs212909 ha-1). Lower system net returns were recorded in conventional rice-rice system (Rs88179 ha-1). Bt. cotton – sesame + black gram (2:4) and Bt Cotton + Soybean (1:2) (BBF)- Sesamum + Groundnut ((2:4) and Maize+soybean (2:4)–tomato were economically superior with REE of 152.71%, 150.81% and 141.45%. Rice- Rice cropping adopted by majority of farmers is less productive and economically inferior indicating wider scope of diversifying existing rice- rice cropping system with high productive, economically viable cropping systems in vertisols of Northern Telangana Zone.

Background: Blackgram [Vigna mungo (L.) Hepper] is one of the most important cultivated legume crops with high nutritive value and agricultural importance. The productivity of blackgram is not adequate to meet the domestic demand of the growing Indian population. Consequently, there is an urgent need for enhancement of productivity through proper agronomic practices. With this background, a research experiment was conducted in a farmer’s field at Pudhupalayam, Coimbatore to investigate the effect of foliar application of PPFM, plant growth regulating compounds and nutrients on growth, yield attributes, yield and economics of irrigated blackgram. Methods: A field experiment was laid out in randomized block design with three replications during 2019 (kharif and rabi) season. The treatments include 100% recommended dose of NPK along with foliar application of diammonium phosphate (DAP), brassinolide (Br), salicylic acid (SA) and pink pigmented facultative methylotrophs (PPFM) with different concentration (1%, 2%, 1 ppm, 2 ppm, 50 ppm, 100 ppm, respectively) in addition to control. PPFM and PGRs were sprayed at 30 and 45 days after the sowing of blackgram. Result: The experiment results of the two seasons study revealed that the application of 100% RDF + PPFM @ 2% recorded higher growth characters viz., plant height (cm), number of branches plant-1, leaf area index and yield attributes viz., number of pods plant-1, number of seeds pod-1, pod weight (g), pod height (cm), 100 seed weight (g) and yield viz., grain yield (kg/ha), straw yield (kg/ha) and harvest index (%). As well as the same treatment recorded higher net return and B:C ratio. Correlation and regression analysis also indicated that the yield attributes had a positive impact on the grain yield with a magnitude of 1.91 and 1.67, respectively. Therefore, application of 100% RDF+2% PPFM spray can be recommended as the best technology to improve the yield and economics of blackgram.

Background: Maize followed by summer pulses is the emerging cropping system in many places in India. Herbicides are the efficient tools for checking weed infestation and their usage is increasing throughout the globe due to increased labour cost and quick weed control. Some herbicides do not degrade quickly and may remain in the soil for weeks, months or years after application and may inhibit the growth of succeeding crops. Methods: Field experiment was conducted in a randomized block design (RBD) during rabi and summer seasons of 2017-18 and 2018-19 to know the residual effect of different herbicides applied in maize on succeeding greengram. Result: The present study revealed that lower density and dry weight of total weeds and higher yield attributes and yield was recorded with the practice of adopting two hand weedings at 15 and 30 DAS, which was however, at par with atrazine 1.0 kg ha-1 as PE fb one HW at 30 DAS, atrazine 1.0 kg ha-1 as PE fb topramezone 30 g ha-1 as PoE and atrazine 1.0 kg ha-1 as PE fb tembotrione 120 g ha-1 as PoE, without any significant disparity among them. Herbicides applied in maize did not alter statistically the enzyme activity and microbial count in the soil at harvest of succeeding greeengram.

A field experiment was conducted during kharif season of 2015 on silty clay loam soil at MPKV, Rahuri (MS), to study the varying nutrient management levels on productivity and economics of different soybean varieties. The experiment was laid out in factorial randomized block design with 15 combinations of three varieties (KDS-344, JS-9305 and KS-103) and five nutrient management levels ( GRDF, 75% GRDF + 0.5% foliar spray of grade IInd at 30 and 45 DAS, 100% GRDF + 0.5% foliar spray of grade IInd at 30 and 45 DAS, N4: 125% GRDF + 0.5% foliar spray of grade IInd at 30 and 45 DAS and 50:75:30 N, P2O5, K2O kg ha-1 + 5 tons FYM ha-1. The variety KDS-344 and application of nutrient management dose 125% GRDF + 0.5 Grade IInd foliar spray at 30 and 45 DAS recorded significantly the highest growth and yield attributes viz., plant height (cm), number of branches, number root of nodules, number of pod plant-1 and weight of seeds plant-1 (g). The variety KDS-344 recorded highest grain and stover (3.66 and 4.64 t /ha) yield and highest economic indices like cost of cultivation (40,623), net monetary returns (87355) and net returns per rupee invested (3.17). The grain yield (4.34 t/ha) and stover yield (4.53 t/ha) of soybean was significantly higher by application of fertilizer dose of 125% GRDF + 0.5% Grade IInd foliar spray at 30 and 45 DAS than rest of treatments, but it was also at par with 75% GRDF + 0.5 Grade IInd foliar spray at 30 and 45 DAS and 100% GRDF + 0.5% Grade IInd foliar spray at 30 and 45 DAS. Similarly, variety KDS-344 and application of nutrient levels of 75 % GRDF + 0.5 % Grade IInd foliar spray at 30 and 45 DAS recorded the highest net returns (82756) and net returns per rupee invested (3.24) in soybean due to reduce in cost of cultivation (36931) and nutrient losses.

A field experiment was conducted during the spring season of 2020 to evaluate the different weed management practices in dry directed seeded spring rice under Prime Minister Agriculture Modernization Project (PMAMP) super zone at Baniyani, Jhapa. The experiment was laid out in randomized complete block design (RCBD) with seven weed management related treatments and three replications. The treatments consisted of pre-emergence application of Pretilachlor, pre-emergence application of Pendimethalin, pre-emergence application of Pretilachlor fb post-emergence butachlor pre-emergence application of Pendimethalin fb post-emergence Bispyribac Na, Sesbania co-culture along with pre-emergence application of Pendimethalin along with two control treatments (weedy free and weedy check). The rice variety Hardinath-1 was used in the experiment. Data regarding the weed flora, weed density, weed dry weight, growth, yield attributes and yield were recorded and analyzed. The highest number of effective tillers per m2 (371.51) and number of grains per panicle (145.43) were obtained in Pendimethalin treated plot and were statistically as par with Sesbania co-culture + Pendimethalin (363.44 m-2 and 140.54 respectively). Higher and statistically similar grain yield was observed in Sesbania co- culture + Pendimethalin (4870kg ha-1) and Pendimethalin treated plots (4780 kg ha-1). The experiment concluded that there was reduction in yield by 66.78 percent due to presence of weed as compared to weed free. Pre-emergence application of Pendimethalin was most beneficial in terms of gross returns, net returns and B:C ratio compared to other weed management practices and hence was most economical.

A field experiment was conducted during rabi seasons of2017-19 at Panwari village, Agra (U.P.) to assess the effect of integrated potassium management on growth, yield and uptake of nutrient in wheat (Triticum aestivum). The experiment was laidout in a randomized block design with seven treatments and three replications. The results revealed that increasing levels of K fertilizers increased the growth and yield attributes up to 90 Kg K2O ha-1 over control. But the growth and yield attributes 0f wheat were maximum with the application of 150 Kg N + 60 Kg P2O5 + 60 Kg K2O + 5 t FYM ha-1. Increasing levels of NPK fertilizers increased the yield of wheat grain and straw over control. The maximum yield of grain(5.48 t ha-1) and straw(9.60 t ha-1) were recorded with N150P60K60FYM5. The increases in grain and straw yield with this treatment were 44.2 and 29.7% over control, respectively. The crop quality in respect of content and yield of protein increased significantly with conjoint use of fertilizers and maximum values were recorded with 150 Kg N + 60 Kg P2O5 + 60 Kg K2O + 5 t FYM ha-1 treatment. Increasing levels of NPK fertilizers up to N 150 P 60 K 90 also resulted in higher uptake of NPK by the crop and highest uptake of N, P, K and S by wheat crop was recorded with N150 P60 K60 FYM5 and the lowest in control. The soil organic carbon, available N, P and K content also improved with N150 P60 K60 FYM5 over control and lowest values of these parameters were recorded in control.
