A field experiment was conducted to study the effect of different planting techniques (conventional drill sowing at 16, 18 and 20 cm row spacing and bed planting with two and three rows in main plots) and weed control treatments (pinoxaden 50 g/ha, ready-mix (RM) of carfentrazone and metsulfuron 25 g/ha and pinoxaden 50 g/ha + RM of carfentrazone and metsulfuron 25 g/ha in subplots) on growth and productivity of wheat. The grain yield under row spacing 18 cm (53.30 q/ha), and 20 cm (52.02 q/ha), and three rows bed planting (51.96 q/ha) were recorded statistically at par with each other and significantly higher than 16 cm (49.37 q/ha) row spacing and two row bed planting (48.53 q/ha). Gross returns (Rs. 95637/ha) and net returns (Rs. 43929/ha) and B:C ratio (1.85) were record-ed higher under 18 cm row spacing compared to other planting techniques. Tank mixed application of pinoxaden 50 g/ha + RM of carfentrazone and metsulfuron 25 g/ha applied at 35 days after sowing (DAS) controlled both grassy and broad leaved weeds effectively with lower values of weed dry matter accumulation (7.67 g/ha) and produced growth parameters, yield attributes and yield (53.16 q/ha) at par with weed free treatment. In light of the results to maximise productivity, 18 cm row spacing may be practiced and tank mix application of pinoxaden (50 g/ha) + RM of carfentrazone and metsulfuron (25 g/ha) is recommended to reduce losses due to complex weed flora in wheat.

Background: Groundnut encounters severe infestation of weed especially during the early stages of growth due to less crop canopy which allows higher weeds growth and thus crop becomes more susceptible to weed competition. During rainy season, effective and economical weed control is not possible through manual and mechanical weeding due to unfavorable soil conditions and also the unavailability of costly labours. Herbicides have been accepted as cost effective tool to manage weed menace in groundnut. The current study aims to study the efficancy of different post-emergence and pre-mix combination of post-emergence herbicides on weeds, growth and yield of groundnut. Methods: The field experiment was conducted at AICRP Weed Management field, Department of Agronomy, Dr. Panjabrao Deshmukh Krishi Vidyapeeth, Akola (M.S.) during three consecutive Kharif seasons of 2015- 2017. The experiment was laid out in Randomized Block Design with ten treatments replicated thrice. The treatments comprised of one pre emergence and five different post emergence herbicides and compared with weed free and weedy check. Result: The results revealed that weed free was found most effective to control weeds in groundnut with lowest weed count, weed dry matter of weeds and maximum gross monetary returns (Rs.117641/ha), net monetary returns (Rs.80894/ha). Among the herbicides, application of Imazethapyr + Imazomox 0.10 kg /ha POE 20 DAS produced less weed count and weed dry matter and highest weed control efficiency (80.68%) and lower weed index (6.71% ) as well as maximum growth, yield attributes and pod yield in groundnut over all the other herbicidal treatments viz. plant height (30.25), dry matter accumulation (18.11g), number of pods/plant (32.35) and pod yield (2448 kg/ha) and highest pooled B:C ratio (3.74).

Agronomic Biofortification

Background and Objective: Sulphur and boron are found as most critical nutrient elements for the better growth and yield of mustard crop however no such concrete information for their uses in field production of this crop is yet to be reported. Therefore, an experiment was conducted to investigate the effect of agronomic biofortification of sulphur and boron nutrients on the growth and yield of mustard crop. Study Design: The experiment was laid out in a Randomized Complete Block Design (RCBD) with three replicates. Place of Study: The experiment was carried out in the Crop Botany Field Laboratory, Bangladesh Agricultural University, Mymensingh. Methodology: Three doses of sulphur (S) viz. 0, 20 and 40 kg ha-1 and three doses of boron (B) viz. 0, 0.5 and 1.0 kg ha-1 and their possible combinations were used as basal doses. Field data were collected from periodic destructive samplings on the plant height, number of leaves and branches per plant, total dry matter accumulation and finally yield components and yield. Results: Sulphur and boron fertilizations significantly influence the plant height, production of branches and leaves per plant, dry matter accumulation and yield attributes and yield of mustard crop. The mustard crop fertilized with 40 kg S ha-1 in combination with 1 B kg ha-1 produced taller plant, higher number of branches and leaves in each plant and higher amount of dry matter per plant while these plant traits were found as minimum when the growing the mustard crops in control plots i.e. the plants received neither sulphur nor boron. Application of sulphur @ 40 kg ha-1 along with boron @ 1 kg ha-1 produced the highest seed yield (2.73 t ha-1) whereas the lowest seed yield (1.08 t ha-1) was found where no sulphur and boron were applied. Conclusion: The result conclude that combine application of sulphur and boron @ 40 and 1 kg per hectare, respectively was found to be most effective dose in enhancing growth and yield of mustard crop.

Crop Weed Competition

Background: Weeds are prime factor that adversely effects on growth, quality and yield of mungbean during summer and rainy season. Being a short duration crop, it faces heavy weed competition right from the early growth stages to harvesting. The critical period of crop weed competition in mungbean was initial 25-30 days, yield may be reduce up to 50-90% if weeds not manage at this stage. Hence, there is a need to find out the successful weed management strategies to realize higher growth and yield. The progressive transformation of agriculture concerning intensive use of herbicides is gaining status in recent years due to easy, lower cost, timeliness and successful controlling weeds. Therefore, keeping above information in view, the present study was undertaken to assess the effect of different weed management practices in summer mungbean under zero tillage condition to find out the better weed management, higher productivity and profitability.Methods: In this field-laboratory investigation during summer season, 2019, different herbicides were applied to manage weeds in mungbean. Eight treatments were applied based on various application windows. In the field and laboratory, the collected samples were determined for crop weed competition, yield attributes, yields and net returns. Result: The results revealed that weed free treatment was recorded lowest weed population at 30 DAS and harvest (1.8 and 2.9), weed dry weight (1.1 and 1.9g) and highest weed control efficiency (96.3 and 94.9%) followed by Pendimethalin (PE) fb one HW and Shaked (Propaquizafop + Imezathyper) application. The similar results also observed in nutrients removed by weeds. Among yield attributes, weed free treatment recorded the longest pod length, no. of pods/plant, no. of seeds/pod and test weight (7.9, 21.0, 9.7 and 43.0g, respectively) which was at par with Pendimethalin (PE) fb one HW and Shaked (Propaquizafop + Imezathyper) application. The magnitude of seed yield was increased under weed free (10.1 q/ha) and Shaked (Propaquizafop + Imezathyper) (9.5 q/ha) treatments by 127.9 and 113.8%, respectively over weedy check. Application of Shaked (Propaquizafop + Imezathyper) recorded highest net returns (Rs 55,079/ha) and B: C (2.8) over rest of the treatments. It can concluded that application of Shaked (Propaquizafop + Imezathyper) @ 2 L/ha at 20 DAS recommended for better weed control, higher yield and net returns of summer mungbean under zero tillage condition.

A field experiment was conducted to evaluate the effect of planting pattern and organic nutrients sources on maize in an intercropping system with cowpea. The treatment consists of four planting pattern (Sole maize, Sole cowpea, 1:1 maize + cowpea and 2:2 paired row maize + cowpea) and four nutrient sources (inorganic, FYM, ambrosia weed biomass and 50% through FYM + 50% through ambrosia weed biomass) allocated to main and sub plots, respectively. Growth parameters of maize did not vary significantly due to planting various planting patterns with cowpea except for dry matter accumulation at harvest. Highest grain, stover and biological yield of maize was also reported from sole maize which was at par with paired row planted maize but significantly higher over the maize intercropped in 1:1 planting pattern with cowpea. All the growth parameters and yield attributes of maize also differed significantly due to application of various sources of plant nutrients except for plant height at 30 DAS, CGR and RGR during 30-60 DAS and cobs per plant and cob length. Maximum grain yield in maize was recorded from inorganic nutrient source which was at par with combined nutrient application through FYM and ambrosia. Protein content ingrain remain at par but nutrient uptake varied markedly and follow the trends of grain and biological yields both due to planting pattern and nutrient sources.

The study was carried out during rabi 2013-2014 in 3 times replicated RBD with three intercropping systems (sole fennel, fennel + fenugreek in 1:1 and 1:2 row ratios) and four sulphur levels (0, 20, 40 and 60 kg S/ha). The results revealed that fennel in 1:2 row ratio recorded significantly higher dry matter and yield attributes of fennel as compared to 1:1 row ratio and sole fennel. Intercropping of fennel in 1:2 row ratio significantly reduced seed (10.42 q/ha), straw and biological yields of fennel over 1:1 ratio and sole fennel. The fennel in 1:1 row ratio could not bring significant variation in growth and yield of fennel as compared to sole fennel. However, when system productivity was compared, intercropping in 1:1 row ratio registered significantly highest net monetary returns (Rs 126471/ha) and land equivalent ratio (1.45) in comparison to intercropping in 1:2 ratio and sole fennel. The sulphur at 40 kg/ha significantly increased growth and yield attributes, seed (15.60 q/ha), straw and biological yields and net returns (Rs 100612/ha) of fennel. Application of 40 kg S/ha in fennel intercropping system was found suitable considering input economy as it recorded 42.07 and 13.37% higher seed yield and 60.71 and 17.40% higher net monetary returns over control and application of 20 kg S/ha, respectively.

Integrated nutrient management (INM) plays an important role to maintain the soil health and improve crop productivity. A field experiment was conducted to study the effect of integrated nitrogen application on transplanted rice. The present investigation was laid out in randomised block design with 10 treatments. Growth parameters like plant height, dry matter accumulation varied significantly among different treatments and the highest value was recorded under the treatment T6 (75% N through fertilizer + 25% N through vermicompost with full dose of P and K). All the yield attributing characters like panicles m-2, grains panicle-1 significantly varied under different treatments. Significantly, higher tiller m-2, grain panicle-1 and panicle length were recorded under T6. Similarly, significantly highest grain yield (4.93 t ha-1) and straw yield (6.01 t ha-1) were observed under T6. Thus, substituting a part of nitrogen fertilizer with organic manure improves soil quality and sustains the crop productivity.

To investigate the response of rainfed maize to sowing methods and NPK levels, an experiment was undertaken during kharif of 2011 and 2012 at Dryland (Kerawa) Agriculture Research Station, Sher-e-Kashmir University of Agricultural Sciences and Technology of Kashmir, Budgam. The experiment was laid out in a randomized block design with combination of 2 sowing methods (flat sowing, 75 cm apart rows, and ridge sowing, 75 cm apart ridges) and 3 fertility levels (60 : 40 : 20, 75 : 50 : 30, and 90 : 60 : 40 N : P2O5 : K2O kg ha−1) with three replications. Various growth characters, namely, plant height, leaf area index, dry matter accumulation, number of days to different phenological stages, and yield, and yield contributing characters namely, cob length, number of grains cob−1, cob diameter (cm), and 100-seed weight (g), were significantly higher with S2over S1during both the years of experimentation. Fertilizer levels F3(90 : 60 : 40) and F2(75 : 50 : 30) at par with one another produced significant increase in growth and yield characters, namely, plant height, leaf area index, dry matter production at different growth stages, cob length, number of cobs plant−1, number of grains cob−1, and 100-seed weight over F1(60 : 40 : 20). Significantly higher grain yield was recorded with fertilizer level F3(90 : 60 : 40) being at par with F2(75 : 50 : 30) and showed significant increase over F1(60 : 40 : 20) with superiority of 5.4 and 5.7 per cent during 2011 and 2012, respectively. The findings of the study concluded that ridge method of sowing of maize with NPK levels of 75 : 50 : 30 kg ha−1showed better performance of crop in terms of growth, yield, and yield attributes.
