A field experiment was conducted during Kharif seasons of 2014 and 2015 at Udaipur (Rajasthan) to find out the effect of weed management on productivity of clusterbean under varying fertility levels. The results revealed that among various weed management practices, two hand weeding 20 and 40 DAS recorded significantly lower weed dry matter, higher weed control efficiency, higher values of yield attributes, seed, haulm and biological yield during both the years over rest of the treatments except sequential application of pendimethalin fb imazethapyr which was statistically at par. Further, application of Imazethapyr fb hand weeding and pendimethalin fb hand weeding also gave comaparable results with pendimethalin fb imazethapyr in terms of weed control efficiency and yields. Among the fertility levels application 20 Kg N + 40 Kg P2O5 ha-1 significantly increased pods plant-1 (24.04), seeds pod-1, (7.12), test weight ( 25.33 g), seed ( 1035 kg ha-1), haulm (2161 kg ha-1) and biological (3196 kg ha-1 ) yield and harvest index ( 31.98 %) of clusterbean over 10 Kg N + 20 Kg P2O5 ha-1 however, it was found statistically at par with fertility level 30 Kg N + 60 Kg P2O5 ha-1. Therefore, clusterbean should be fertilized with 20 Kg N + 40 Kg P2O5 ha-1 and weeds must be controlled with pendimethalin (PE) fb imazethapyr 0.1 kg ha-1 20 DAS .

An experiment was conducted for 2 years (2018 and 2019) at Oilseed Research Farm, Kalyanpur, C. S. A. University of Agriculture and Technology, Kanpur, Uttar Pradesh, India to evaluate the effect of nutrient management practices on growth and yield of pearl millet (Pennisetum glaucum (L) R. Br. Emend. Stuntz.). Highest yield was observed in 5t FYM/ha application over control. Each unit increase in N level led to significant increase in growth, yield attributing characters and yield of pearlmillet. The maximum grain yield (24.2q/ha) was recorded with highest N level. Combined inoculation of Azospirillum + PSB increased the growth, yield attributes and yields significantly. The monetary returns were found in similar trends. Application of organic manure and bio-fertilizers resulted in desirable post-harvest soil status with more organic carbon (OC), Nitrogen (N), Phosphorus (P) and Potash (K).

Background: Blackgram is an important crop among kharif pulses and is usually grown on marginal and sub-marginal lands without proper weed management under rainfed situation. Broad bed furrows had greater influence on plant growth over farmers practice. Weed management through mechanical or manual is normally tedious, labour consuming and costlier. Keeping this in view, the present study was envisaged to investigate integrated effect of land configuration and weed management regimes on productivity of urdbean. Methods: A field experiment was carried out during kharif seasons of 2016 and 2017 at Regional Agricultural Research Station, Lam, Guntur on effect of land configuration and weed management on performance of urdbean (Vigna mungo L.Hepper). The treatments included two land configurations i.e., flat bed and broad bed furrow method allotted as horizontal plots and four weed management practices i.e., weedy check, pendimethalin 30 EC @ 1.0 kg a.i ha-1 PE, imazethapyr 10% SL @ 55 g ha-1 at 15-20 DAS and pendimethalin 30 EC @ 1.0 kg a.i ha-1 PE fb imazethapyr 10% SL @ 55g ha-1 at 15-20 DAS allotted as vertical plots replicated four times in a strip plot design. The comparison of treatment means was made by critical difference (CD) at P less than 0.05 by using standard statistical procedures. Result: Based on the results, it can be concluded broad bed method of land configuration proved its superiority over flat bed method by producing 12.8 per cent higher grain yield besides empowering growth and yield attributes. Among the weed management practices, the highest grain yield (1280 kg ha-1) recorded with pendimethalin 30 EC @ 1.0 kg a.i ha-1 PE fb imazethapyr 10% SL @ 55g ha-1 at 15-20 DAS along with maximum monetary returns and B:C can be recommended for urdbean.

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.

Plant nutrients and soil moisture are considered some of the most important factors affecting physiological characters and grain yield of maize. Therefore, a field experiment was conducted at UBKV, Cooch Behar, West Bengal during 2013 and 2014 to study the effects of moisture conservation and nutrient management practices on growth and yield of maize (Zea mays L.). The experiment was laid out in a split –plot design with three replications. Four levels of moisture conservation practices M0: without irrigation and without mulch, M1: irrigation as and when required, M2: dry weed biomass mulch @5.0t ha-1 M3: FYM mulch @ 5.0 t ha-1 were assigned to main plots and four levels of nutrient management N1: 100% RDF 80:40:40 kg ha-1 of N:P2O5: K2O N2:100% RDF + phosphate solubilising bacteria (PSB) + Azotobacter N3:75% RDF+ PSB + Azotobacter + vermicompost (VC) @ 5.0 t ha-1 and N4:50% RDF + PSB + Azotobacter + 50% vermicompost @ 2.5t ha-1 for sub plot. Among the moisture conservation practices, application of irrigation recorded the highest growth, yield attributes, yield and harvest index followed by FYM mulch and dry weed bio-mass mulch. Similarly, N, P and K uptake of maize was recorded highest under irrigation followed by FYM mulch; dry weed bio mass mulch and lowest N, P and K uptake were recorded under without irrigation and mulch. Among the nutrient management practices the highest growth, yield attributes, yield, harvest index and N, P & K uptake were recorded under 75% RDF + PSB + Azotobacter + vermicompost @ 5.0 t ha-1 followed by 100% RDF + PSB+ Azotobacter & 100% RDF and lowest were recorded under 50% RDF + PSB + Azotobacter + 50% vermicompost 2.5 t ha-1 . Likewise, maximum benefits were recorded under 75% RDF + PSB+ Azotobacter + vermicompost @ 5.0 t ha-1 and lowest net return and return per rupee invested were recorded under 50% RDF + PSB + Azotobacter + 50% vermicompost 2.5 t ha-1. From this study, maize grown with irrigation and supplied with 75% RDF + PSB + Azotobacter + vermicompost @ 5.0 t ha-1 is found the best for obtaining overall gain on a sustainable basis.

Organic Weed Management

Background: Weeds are widely reported as a key constraint in organic agriculture. Soybean-chickpea is important cropping sequence adopted in Maharashtra State under irrigated condition. Weed management is a serious problem in both the crop and it mostly controlled through chemical weed control. Today, widespread use of herbicides has resulted in purporated environmental and health problem as well as residual problems to succeeding crops. Now a days residue free food requirement is high. In organic farming cultural and mechanical methods are necessary to break the weed cycle. So, keeping this point in view present investigation was carried out to evaluate organic weed management practices on growth, yield and weed control in soybean-chickpea sequence under irrigated condition. Methods: A field experiment was conducted during Kharif and rabi seasons of 2017-18 and 2018-19. The present investigation consisted of ten weed management practices viz. two hand weeding at 20-25 and 45-50 DAS, one hoeing 20-25 DAS + one hand weeding at 45-50 DAS, soybean + sunhemp incorporation after 35-40 DAS in kharif season and chickpea + safflower (2:1) in rabi season, stale seed bed + reduced spacing + 2 tonne of wheat straw + one hand weeding at 25 DAS, soil mulch at the time of sowing + one hand pulling at 25 DAS, incorporation of neem cake 1.5 tonne/ ha 15 days before sowing + one hand weeding at 25 DAS, soil solarization with 25 μ polythene mulch during summer + one hand weeding at 25 DAS, mulching with straw, weed free and weedy check. Result: The higher values of growth attributes was recorded by weed free treatment which was on par with two hand weeding at 20-25 and 45-50 DAS and soil solarization with 25 μ polythene mulch during summer + one hand weeding at 25 DAS and significantly superior over rest of the treatments during both the year study. Application of stale seed bed with reduced spacing and 2 tonne of wheat straw along with one hand weeding 25 DAS recorded higher soybean equivalent yield followed by soybean + sunhemp incorporation (35-45DAS) in kharif and chickpea + safflower (2:1) in rabi season during both the year. The lower weed density, dry weight and highest weed control efficiency at 40 days after sowing for both monocot and dicot weeds was recorded by weed free treatment followed by soil solarization with 25 μ polythene mulch during summer + one hand weeding at 25 DAS in soybean and chickpea during both the year.
