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.

A field trial was conducted during two consecutive summer seasons of2012 and 2013 at ICAR-Central Potato Research Station, Shillong, Meghalaya to evaluate the integration of nutrient sources on productivity and soil health under rainfed potato cultivation in north eastern hill region of India. There were six treatments of integrated nutrient management viz., 100% Recommended dose of fertilizers,75% RDF through synthetic fertilizers and 25% recommended dose of nitrogen (RDN) through FYM, 50% RDF and 50% RDN through FYM, 25% RDF and 75% RDN through FYM, 100% RDN through FYM and control (no application of any sources of nutrients). The experiment was laid out in randomized block design with four replications. Nutrient management practices showed the significant improvement on growth and yield attributes of potato over control plot. Highest productivity of potato tubers (t/ha) was noticed with application of 75% RDF through synthetic fertilizers along with 25% RDN through FYM. Similarly, the maximum net return was associated with application of 75% RDF and 25% RDN through FYM under investigation. Application of 75% Recommended dose of nutrients through synthetic fertilizers in combination with 25% Recommended dose of nitrogen through FYM was more profitable for sustainable production of potato in the north eastern hill region of India.

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.

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.

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).

Aims: To evaluate the effects of jute agrotextile mulches on yield and yield attributes, dry matter accumulation, water use efficiency as well as accumulated agrometeorological indices and thermal utilization of groundnut. Place and Duration of Study: The study was conducted in the experimental farm of Bidhan Chandra Krishi Viswavidyalaya, West Bengal, India during kharif season of 2017 and 2018. Methodology: The experiment was carried in randomized block design with five treatments each of which was replicated four times Groundnut (variety J L-24) as a test crop. The treatments (T), composing different strength of jute agro textile (JAT) used as mulching material were as follows: T1: 1000 GSM JAT, T2: 800 GSM, T3: 600 GSM, T4: 400 GSM JAT and T5: farmer's practice (control) where GSM is gram per square meter. All the data regarding the yield, yield attributes, water use efficiency and thermal utilization of the crop were recorded accordingly. Results: Response of pod yield over control were 24.26 q/ha, 26.44 q/ha, 20.98 q/ha and 18.25q/ha in T1, T2, T3, T4, T5 respectively. Though all the treatments showed increment over control, the highest result was found in T2 and a further increase in strength of JAT showed a decrement in all aspects. The water use efficiency, at an average, increased by 69.12% due to the various treatments over control. Heat unit and thermal units use efficiencies were also highest in treatment T2 which showed the most accurate utilization of thermal indices. Conclusion: Therefore, among all the treatments T2 exhibited the most promising effect on improving yield and other attributes along with maintaining sustainability as it might have provided the most favourable soil condition compared to other mulches for groundnut.

Leguminous Crop

Soybean (Glycine max) is a leguminous crop grown worldwide for its dual qualities viz. high protein and oil content. It contains about 40-42% protein and 20-22% oil and is one of the major cash crop of rainy season.The plant growth parameters like plant height, leaf area index (LAI) and dry matter accumulation of soybean increased with application of nitrogen from 30-80 kg N ha-1. Nodule number and nodule dry weight increased with application of 40 kg N ha-1and decreased afterwards whereas, yield and yield attributes of soybean increased with the application of nitrogen upto 100 kg ha-1. Application of nitrogen from 40-80 kg N ha-1as basal dose resulted in increase in protein content. The split application of nitrogen as basal and at reproductive stages also resulted in increase in protein content. However, oil content decreased with increasing level of nitrogen. The oil content increased with application of nitrogen upto 40 kg N ha-1. Application of nitrogen also improved soil properties like organic carbon, available NPK and saturated hydraulic conductivity.
