A field experiment was conducted during kharif season of 2016 at Mahatma Gandhi Chitrakoot Gramodaya Vishwavidyalaya, Chitrakoot, Satna (M.P.) to study the efficacy of different herbicides against weeds in mungbean. The weed density recorded at 30 and 60 DAS was significantly lower under pendimethalin 30 EC + imazethapyr 2 EC (Ready mix) 0.75 kg/ha as pre-emergence (PE) followed by pendimethalin PE. However, significantly lower weed dry weight and statistically superior weed control efficiency were noted in twice hand weeding at 20 DAS and 40 DAS and pendimethalin + imazethapyr (R.mix.) 0.75 kg/ha at same stages of crop (30 and 60 DAS). While, yield attributes viz. pods/plant (21.8) was significantly higher in plot treated with imazethapyr 10 SL @ 40g/ha applied at 20 DAS and statistically at par with imazamox 35 WG+ imazethapyr 35 WG 60g/ha applied at 20 DAS and clodinafop - propargyl 8% + aciflourfen - sodium 16.5% (WP) 187.5 kg/ha applied at 20 DAS. Application of clodinafop - propargyl 8% + aciflourfen - sodium 16.5% (WP) 187.5 kg/ha at 20 DAS produced significantly maximum seed yield (531 kg/ha) of mungbean closely followed by imazethapyr 10 SL @ 40g/ha at (528 kg/ha) and pendimethalin 30 EC + imazethapyr 2 EC (R.mix) 0.75 kg/ha (521 kg/ha). However, stover yield (2699 kg/ha), gross returns (`58464/ha) and net returns (`43163/ha) were obtained significantly superior under clodinafop - propargyl 8% + aciflourfen - sodium 16.5% (WP) 187.5 g/ha.

A pot experiment was carried out in the nethouse of Soil Science Division, Bangladesh Agricultural Research Institute, Joydebpur, Gazipur during 2014-2015 through 2015-2016. The design of the experiment was factorial randomized completely block design with 4 replications. The objectives of the study were to evaluate the potential of Arbuscular mycorrhization (AM) on the germination, yield and yield attributes of lentil treated with different concentration of sodium chloride (NaCl). Five NaCl treatments (0, 1, 2, 3 and 4%) possessed NaCl level as the first factor that were treated with soils before sowing of lentil seeds overriding or pivotal pulse crop in Bangladesh. The second factor consists of mycorrhizal and non-mycorrhizal treatments. Mycorrhizal plants showed better performance in terms of germination %, yield and yield contributing characters than non-mycorrhizal plants. With increasing NaCl concentration germination %, yield and yield contributing characters in the rhizosphere soil, decreased significantly (p<0.01). Interaction effects of mycorrhizal inoculation and NaCl on germination %, growth and yield of lentil were appeared to be statistically non-significant. The highest germination (96.25% in 2014-2015 and 92.50% in 2015-2016), seed yield (6.45 g pot-1 in 2014-2015 and 5.89 g pot-1 in 2015-2016), and stover yield (9.55 g pot-1 in 2014-2015 and 8.58 g pot-1 in 2015-2016) was found in NaCl 0% + AM treatment. The lowest germination %, seed yield and stover yield was found in NaCl 4% treatment. Mycorrhizal inoculation increased seed yield on an average by 31.85% during 2014-2015 and 63.71% during 2015-2016, and increased stover yield on an average by 48.56% during 2014-2015 and 63.55% during 2015-2016 over non-mycorrhizal inoculation. Therefore, it can be concluded that mycorrhizal inoculation increases germination %, growth and yield of lentil over non-mycorrhizal inoculation. The Agriculturists 2017; 15(1) 156-169

A field experiment was conducted during kharif season 2012 and 2013 at Rajmata Vijayaraje Scindia Krishi Vishwa Vidhyalaya RVSKVV, College Farm Gwalior (M.P.) to asses the suiTable method for weed control in soybean. On the basis of two years pooled data results weeding twice at 20 and 40 DAS significantly highest growth, yield attributes and seed yield as compared to the un-weeded control and was at par with pendimethalin (750 g a.i./ha) + one hand weeding, trifluralin (1000 g a.i./ha) + one hand weeding at 20 DAS and imezathapyr(100 g a.i./ha) + one hand weeding at 40 DAS. These treatments also recorded lower weed dry biomassand higher weed control efficiency. Pendimethalin (750 g a.i./ha) + one hand weeding at 20 DAS resulted higher net return (` 63500) and B:C (2.58) ratio followed by trifluralin + one hand weeding and hand weeding twice at 20 and 40 DAS. In addition to hand weeding twice, pre emergence herbicide Pendimethalin (750g a,i/ha) + one hand weeding at 20 DAS can be effectively used as an alternative for controlling weeds for obtaining optimum seed yield in soybean.

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 .

Abstract Cluster bean (Cyamopsis tetragonoloba L.) yield have plateaued due to reduction in rainfall and rise in temperature. Therefore, its production cycle could not get appropriate water and temperature. It becomes important to standardize sowing time and plant spacing of cluster bean in changing climate scenario to get higher productivity. Therefore, a field study was conducted to evaluate the effect of four sowing times (15th May, 1st June, 15th June, and 1st July) and three plant spacings (10, 12 and 15 cm) on crop growth, yield, and physiological functions of cluster bean genotype BR-2017. The sowing times (15th May, 1st June, 15th June, and 1st July) were placed in the main plot while plant spacing (10, 12 and 15 cm) were maintained in subplots. Results showed that 1st June sowing performed better over 15th May, 15th June, and 1st July while plant spacing 15 cm about in all sowing times showed higher results on growth and yield parameters of cluster bean over plant spacing 10, 12, and 15 cm. The 1st June sowing time at 15 cm plant spacing showed 8.0, 22.7, and 28.5% higher grains pod-1 as compared to 15th May, 15th June, and 1st July sowing respectively. The chord diagram clearly indicates that the crop has received optimum environmental conditions when sown 1st June over other sowing times. In conclusion, 1st June sowing with 15 cm plant spacing could be a good option to achieve maximum productivity of cluster bean under changing climate scenario.

A field experiment was conducted during kharif 2013 and 2014 to study the effect of row spacing and sowing time on seed yield, galactomannan and protein content and nutrient uptake of guar in semi arid climate of Southern Telangana. The crop sown at row spacing of 30 cm recorded significantly higher seed yield than that of 45 cm and 60 cm spacing. Production and rainfall use efficiency and harvest index besides growth and yield attributes, galactomannan and protein yields, N, P and K uptake were also significantly higher at 30 cm spacing. Sowing of guar during first or second fortnight of July resulted in significantly higher seed yield than first fortnight of August sowing. Production efficiency, plant height, number of clusters plant-1 and protein yield followed the similar trend of seed yield. Negative relationship was observed between galactomannan content and sowing time. Though powdery mildew infection was higher in early sown crop and close crop spacing, higher plant population and biomass production resulted in higher seed yield of guar when compared to late sown crop and wider spacing.

Abstract This study explores the effects of the pre-emergence herbicides alachlor (1680; 2400 g ha-1) and trifluralin (720; 1200 g ha-1), the post-emergence herbicides bentazone (360; 480 g ha-1) and haloxyfop (250; 375 g ha-1) and their combinations, along with the effect of seed hydro-priming on weed control, growth and yield of sesame (Sesamum indicum L.). Hydropriming reduced the interval from planting to seedling establishment, increased the seedling dry weight and the crop grain yield. Based on grain yield, 720 g ha-1 trifluralin followed by 250+720 g ha-1 holoxyfob + trifluralin, 250 +1680 g ha-1 holoxyfob + alachlor, 2400 g ha-1 alachlor, and 1680 g ha-1 alachlor, all combined with priming, were the best treatments. The results showed that proper combination of pre- and post-emergence herbicides along with seed priming could be used to control the weeds in the sesame and obtain seed yield comparable with weed-free conditions

A field experiment was conducted during the rainy (kharif) season of 2013 and 2014 to find out the effect of “influence of mulching practices, varieties and fertility levels on growth and productivity of clusterbean ,,.The results revealed that the plastic mulch significantly increased the growth and yield characterstics, seed yield as well as economics over the weed biomass mulch and no mulch. Variety HG-563 recorded significantly higher growth characterstics, yield attributing, seed yield and economics as compared to RGC-1055. Among the fertility levels, application of 75% RDF + VC 5 t/ha resulted in significantly higher growth characterstics, yield attributing, seed yield and economics over all the remaining fertility levels. Thus, it can be concluded that in clusterbean (variety HG-563), adoption of plastic mulch along with RDF 75%+ 5 t/ha vermicompost is recommended for erratic and scarce rainfall as well as low sustainability of soil.
