A field experiment was conducted during kharif season of 2015 at Zonal agricultural research station, Jhabua with the objective to assess the bio-efficacy of atrazine herbicide against complex weed flora and yield of maize crop. The experiment consisted of six treatments, was laid out in randomized block design with three replications. Results revealed that all the weed control treatments significantly reduce the weed density and weed dry matter at 30 and 60 DAS. Atrazine 50% WP @ 1 kg/ha significantly reduced the weed count of grassy as well as broadleaved weeds at 30 and 60 DAA and found at par with Atrazine 50% WP @ 1.5 kg/ha and Atrazine 50% WP @ 2.0 kg/ha. However, better efficacy was observed with higher dose of atrazine viz., Atrazine 1.5 kg and 2.0 kg/ha. Hand weeding was also found as an effective tool for controlling the weed biomass at early stage of observation (30 DAS) but on later stage of crop it proves less effective due to emergence of weeds which further reduce the yield. Further, maize yield (43.43 q/ha) was also found significantly superior in Atrazine 1.0 kg/ha as compared to Atrazine 0.5 kg/ha, hand weeding a 20 DAS and control plot and found at par with higher doses of atrazine. Highest net return of Rs 43203/ha and B:C ration of 3.43 was observed in Atrazine 1.5 kg/ha.

A field trial was conducted to assess the performance of blackgram cultivars to row spacings and molybdenum doses at the Instructional-cum-Research Farm, Indira Gandhi Krishi Vishwavidyalya, Raipur (Chhattisgarh), under rainfed conditions during kharif season of 2011. The treatments comprised of three varieties viz., Indra urd-1, RU-03-16 and RU-03-52; two row spacings viz., 30x10 cm and 45 x 10 cm and three treatments of molybdenum viz., control, 4 g/kg seed and 4 g/kg seed + two spray of urea @ 2%. The experiment was laid out in factorial randomized block design (FRBD) with three replications. Results revealed that all the growth and yield attibutes such as number of branches/plant, number of leaves/plant, seeds/plant, seed yield (781 kg/ha), biological yield (2736 kg/ha) and harvest index (29.71%) noticed significantly higher under cultivar Indra urd-1. Similarly, maximum production efficiency (9.52 kg/ha/day), economic efficiency (Rs. 218.82/ha/day) and gross returns (Rs. 32,335/ha) were also recorded in Indra urd-1 as compared to rest of the cultivars. Further results showed that all the growth and yield attributes viz., number of branches/plant, number of leaves/plant, seeds/plant, seed yield (778 kg/ha), biological yield (2653 kg/ha) and harvest index (29.10%) recorded significantly higher in row spacing of 30 x 10 cm as compared to 45 x 10 cm. Maximum production efficiency (9.49 kg/ha/day), economic efficiency (Rs. 216.44/ha/day) and gross returns (Rs. 32,107/ha) were also recorded in 30 x 10 cm. Application of molybdenum @ 4 g/kg seed along with 2% urea spray twice gave highest seed yield (810 kg/ha), biological yield (2698 kg/ha) and harvest index (29.25%) over control and seed treatment with molybdenum @ 4 g/kg. Similarly, application of molybdenum + 2% urea spray twice gave maximum production efficiency (9.88 kg/ha/day), economic efficiency (Rs. 226.49/ha/day) and gross returns (Rs. 33,293/ha).

India is the largest producer and consumer of pulses in the world accounting for about 29 per cent of the world area and 19 per cent of the world’s production. In order to achieve self-sufficiency in pulses, the projected requirement by the year 2025 is estimated at 27.5 MT. To meet this requirement, the productivity needs to be enhanced to 1000 kg/ha, and an additional area of about 3-4 Mha has to be brought under pulses besides reducing post-harvest losses. This uphill task has to be accomplished under more severe production constraints, especially abiotic stresses, abrupt climatic changes, emergence of new species/ strains of insect-pests and diseases, and in-creasing deficiency of secondary and micronutrients in the soil. This requires a two-pronged proactive strategy, i.e. improving per unit productivity and reducing cost of production. The yield levels of pulses have remained low and stagnant, also area and total production. Among the pulses pigeon pea is second most important grain-legumes and major constraints in pigeon pea production is mostly grown in grown on marginal lands under rainfed agriculture and without nutrient management, hence are prone to abiotic stresses. Therefore, it is essential for higher production and productivity of pigeon pea, use of high yielding varieties which suitable for intercrop as well as sole cropping system with best nutrient management practices.

A field experiment was conducted at ZARS, Jhabua (M.P.) during kharif 2014 to find out most suitable and efficient method of weed control in soybean. The experiment consisted of nine treatments laid out in randomized block design with three replications. All the weed management practices led to significant reduction in density and dry matter of weeds as compared to weedy check. Two hand weeding (20 & 40 DAS) recorded lowest weed density (4.9/ m2), weed dry matter (22.35 g/m2) with highest weed control efficiency of 59.67% and found at par with the application of Chlorimuron Ethyl @ 9gm /ha + Quizalofop-p-ethyl @ 50 g /ha (density 5.48/ m2, dry matter 26.62 g/m2 and WCE of 51.97%) and Imazethapyr @ 35 g /ha + Imazamox @ 35 g/ha (density 6.13/ m2, dry matter 26.00 g/m2 and WCE of 53.08%). Maximum yield of 1782 kg/ha was recorded in two hand weeding (20 & 40 DAS) closely followed by Chlorimuron Ethyl @ 9gm /ha + Quizalofop-p-ethyl @ 50 g /ha (1723 kg/ha) and Imazethapyr @ 35 g / ha + Imazamox @ 35 g/ha (1697 kg/ha). Reduction in soybean yield in weedy check to be recorded is 38.78 per cent when compared to weed free and 36.68 per cent in comparison to Chlorimuron Ethyl @ 9gm /ha + Quizalofopp-ethyl @ 50 g /ha. However, highest Benefit to Cost ratio is recorded in Chlorimuron Ethyl +Quizalofop-p-ethyl (3.26) closely followed by Imazethapyr + Imazamox (3.22) and Weed free (3.21).

The field experiments were conducted during kharif2013, 2014 and 2015 at Research Farm of Zonal Agricultural Research Station, Jhabua to study the effect of nutrient management practices on yields, nutrient content and economics of the soybean grown under rainfed condition of Jhabuahill. The experiment laid out in randomized block design with nine nutrient levels viz., T1-control, T2- vermicompost (5t/ha), T3-FYM (10 t/ha), T4-Recommended dose of fertilizers (RDF=20 N: 30 P2O5: 20 K2O kg/ha), T5-50% RDF + Rhizobium + PSB, T6- 50% RDF + 50% vermicompost, T7-50% RDF + 25% vermicompost + Rhizobium + PSB, T8- Rhizobium culture + PSB and T9- 50% vermicompost + Rhizobium + PSB. Results revealed that application of application of 50% RDF + 50% vermicompost(T6) gave significantly highest seed yield (22.62 q/ha), straw yield (23.86 q/ha), biological yield (46.48), gross return (Rs. 69,230/ha), net return (Rs. 49,571/ha), production efficiency (20.56 kg/ha/day) and economic efficiency (450.64 Rs./ha/day) as compared to control. Whereas maximum B:C ratio (3.84) was recorded in 100% RDF followed by vermicompost @ 5 t/ha. Similarly, higher nutrient content (N, P and K) in seed as well as straw and their uptake were recorded under 50% RDF + 50% vermicompost. The highest protein content (41.99%) and protein yield (94,864 kg/ha) was also observed with the application of 50% RDF + 50% vermicompost. Hence, application of 50% RDF + 50% vermicompost better for obtain higher yields, economics and nutrient content and their uptake of soybean under rainfed condition of Jhabuahill of Madhya Pradesh

Characteristically boro rice is winter season, photo-insensitive, transplanted rice cultivated on supplemental irrigation, often under conditions, where farmers’ are not able to take any other rabi season crop. Butachlor, pretilachlor, bispyribac-sodium and anilofos are the most commonly used herbicides for control of weeds in boro rice. Weed competition is one of the prime yield limiting biotic constraints resulting in yield reduction to the tune of 28 to 45%. Echinochloa spp., Cynodon dactylon, Portulaca quadrifida and Cyperus spp. are the major weeds responsible for yield reduction in boro rice. However, continuous and indiscriminate use of herbicides for a longer period may result in buildup of problematic weeds and also development of herbicide resistance in weeds. It is therefore, necessary to review the performance of promising herbicides for chemical weed management to improve the production and productivity of boro rice under the climate change scenario.
