Influence of crop management practices on late sown toria (Brassica campestries var. toria) under rainfed rice-fallow situation of Assam

Journal of oilseed Brassica (2017)

B. N. Gogoi K Kurmi K Thakuria NJ Ojha Susanta Dutta

A field experiment was conducted under rainfed condition during the rabi season of the year 2014-2015 and 2015-2016 at the Instructional-cum-Research farm, Assam Agricultural University, Jorhat, India to study the performance of recently developed late sown toria var. JT-90-1 (Jeuti) under different dates of sowing, seed rates and method of sowing in medium land rice-fallow situation. The experiment was conducted in split plot design with three replications keeping the dates of sowing in the main plots and combination of seed rates and method of sowing in the sub plots. The treatments consisted of 4 sowing dates, viz. 1st, 8th, 15th and 22nd December; 3 seed rates, viz. 6, 8 and 10 kg/ha and 2 methods of sowing viz. line sowing at 25 cm apart and broadcasting. The highest seed yield of 724.3 and 742.1 kg/ha, stover yield of 2268.4 and 2296.5 kg/ha and seed oil content of 35.1 and 35.2% were recorded in 1st December sown crop which were significantly higher over other dates of sowing in first and second year, respectively. The extent of decrease in seed yield was 9.2 to 34.6% and 6.8 to 32.6% for 7 and 21 days delay in sowing from 1st December (D1) during the first and second year, respectively. The seed rate of 10 kg/ha (S3) recorded significantly higher yield of seed, stover, seed oil content over that of 6 and 8 kg/ha. In case of sowing method line sowing was found to be better than broadcasting in all growth and yield attributing characters. The crop recorded highest gross return (50,223.4 /ha), net return (33,013.4 /ha) and benefit-cost ratio (2.9) when sown on 1st December with seed rate of 10 kg/ha in lines made at 25 cm apart.

Fodder productivity and profitability of different maize and legume intercropping systems

The Indian Journal of Agricultural Sciences (2019)

Devendra Singh Ginwal Rakesh Kumar Hardev Ram Susanta Dutta MALLIK ARJUN

The current trend in global agriculture is to search for highly productive, sustainable and eco-friendly cropping systems. Intercropping of cereals with legumes is a recognized practice for economizing the use of nitrogenous fertilizers and increasing the productivity, quality, and profitability particularly in commercial grain crops but possibilities of fodder production in these intercropping systems is less explored. Availability of green fodder with improved quality to animals is the key to success of dairy enterprises and it is difficult to maintain the health and milk production of the livestock without supply of the quality green fodder. The growing of fodder crops in mixture with legumes has potential to improve palatability and digestibility of fodder (Kumar et al. 2018, Kumar et al. 2016). It is fact that about 65-70% of the total cost of livestock farming is attributed to feeding. However, green fodder production is a good way in order to curtail the cost on feed and fodder resources for sustainable livestock production. At present, the country is facing a net deficit of 35.6% green fodder, 10.95% dry crop residues and 44% concentrate feed ingredients. At the current level of growth in forage resources, there will be 18.4% deficit in green fodder and 13.2% deficit in dry fodder by the year 2050 (Anonymous 2015). The main objective of intercropping has been to maximize use of resources such as space, light and nutrients as well as to improve fodder quality and quantity. When legumes are used as intercrops, they provide beneficial effect on soil health by fixing atmospheric nitrogen, improving physical, chemical and biological properties. Hence, present study was undertaken in order to to assess the productivity, soil nutrient status and economics of different forage maize-legumes based intercropping systems.

Effect of Organic and Inorganic Nutrient Sources on Yield and Quality of Fodder Cowpea [Vigna unguiculata (L.) Walp.]

Indian Journal of Animal Nutrition (2019)

Susanta Dutta Magan Singh Rakesh Kumar Nirmalendu Basak Goutam Mondal

A field experiment was conducted to ascertain the effect of organic and inorganic nutrient sources on yield and quality of fodder cowpea [Vigna unguiculata (L.) Walp.] during kharif, 2017 at Research Farm of Agronomy Section, ICAR-National Dairy Research Institute, Karnal. The experiment was laid out in Randomized Block Design with twelve nutrient combinations and replicated thrice. Nitrogen, phosphorus, potassium was applied in the form of urea, SSP and MOP, respectively and four different biofertilizers were used viz. rhizobium, phosphate solubilizing bacteria (PSB), potassium solubilizing bacteria (KSB) and zinc solubilizing bacteria (ZnSB). Application of RDF (N, P, K) along with biofertilizers (Rhizobium, Phosphorus Solubilizer Bacteria, Potassium Solubilizer Bacteria and Zinc Solubilizer Bacteria) Treatment [T6] gave significantly (P<0.05) higher green fodder yield (334.5 q ha−1), Dry matter content (17.80%) and dry matter yield (59.5 q ha−1). Application of 2/3rd RDF along with biofertilizers (Rhizobium, PSB, KSB and ZnSB), [T7] significantly (P=0.05) enhanced the quality parameters of fodder cowpea like crude protein (18.30%), ether extract (3.48%) and total ash content (8.82%) while insoluble crude protein (NDICP and ADICP), organic matter and fiber fractions (NDF, ADF, ADL) were significantly (P<0.05) lowered. However, lignin content was comparable among the treatments. Therefore, it is concluded that reduction of one third RDF along with additional biofertilizers gave more improved quality fodder than rest of the treatments.

Susanta Dutta Magan Singh Rajesh Kumar Meena Santosh Onte Nirmalendu Basak

An experiment was conducted to evaluate the varying organic and inorganic nutrient sources on fodder cowpea [Vigna unguiculata (L.) Walp.] in the kharif of 2017 at ICAR- NDRI, Karnal. The result revealed that application of 100% RDF (N,P,K) along with biofertilizers (rhizobium, PSB, potassium and zinc solubilizer bacteria) (T6) gave significantly (P less than 0.05) higher in plant height (204.6 cm), primary branches (6.1), root length (24.47 cm), green matter yield (334.5 q ha-1), CGR (8.13 g m-2 day-1), RGR (4.68 g g-1 day-1), K content (1.45%) in plant, P uptake (23.01 kg ha-1) and K uptake (86.04 kg ha-1) and available Zn status (0.465 ppm) in soil, after harvesting of the crop. However, N content (2.93%) in plant, N uptake (172.51 kg ha-1) and Zn uptake (192.03 g ha-1) was maximum with the application of 66.67% RDF along with biofertilizers consortium (T7). Application of 100% RDF along with PSB (T3) recorded highest number of nodule (33), P content in plant (0.389%) and available P status (24.76 g ha-1) in soil, after harvest. Further studies that, available N status (208.03 kg h-1), K status (221.27 kg ha-1) in soil, after harvest and Zn content (33.31 ppm) in plant were significantly higher with these treatments like T8 -15 N, 60 P2O5, 40 K2O kg ha-1 along with rhizobium, T4 -100% RDF along with K solubilizer and T11 -FYM 5 t ha -1 with biofertilizers, respectively. In context of the economics of fodder cowpea production, highest gross return (Rs. 53525 ha-1) was obtained from T6 while maximum net return (Rs. 31351 ha-1) and benefit-cost ratio (1.45) were worked out maximum with the treatment T7.

Sustainable Crop Production Using Plant Growth Promoting Rhizobacteria: A Green Technology

Apple Academic Press eBooks (2024)

Magan Singh Dinesh Kumar Susanta Dutta Mange Ram Yadav Vishnu D. Rajput

Problems arise after the green revolution owing to excess use of agrochemicals creates a challenge to sustain crop productivity. To counteract this challenge, the use of different forms of organic nutrient sources has been initiated throughout the world. As a component of organic nutrient sources, the plant growth promoting rhizobacteria (PGPR) is getting popularity in these days. PGPR is the group of soil bacteria which maintains the plant health through aids in better growth and development mechanism in the plant system. It helps to improve the nutrient acquisition through nitrogen fixation, solubilization of phosphorus, potassium, secondary nutrients as well as micronutrients and also through production of siderophore and phytohormones like Indole 803-acetic acid, gibberellin, and cytokinin which leads to better crop growth. PGPR also have a significant importance on development of systemic resistance against the plant pathogens. Hence, it improves soil health (by enriching the physico-chemical and biological properties) and plant health which in turn enhance the sustainability in crop production on a long-term basis. Different crops showed the significant increment in its growth, yield, and nutrient content as a result of plant–PGPR interactions. It was further noticed that co-inoculation of different strains of PGPR has shown better results as compared to single inoculation. Such a capability of PGPR aids in reducing the use of mineral fertilizers which ultimately saves the inputs cost for crop production and reduces the soil as well as environment pollution.

Combining ability studies for yield and component traits in chilli (Capsicum annuum L.)

Progressive Agriculture (2003)

S. K. Pandey J. P. Srivastava B. Singh Susanta Dutta

Combining ability for yield and its component traits in chilli was studied in a line x tester mating system. The mean squares due to females, males and female x male were highly significant for all the seven characters, namely plant height, no. of primary branches plant-1, no. of secondary branches plant-1, no. offruits plant-1, fruit length, fruit width and yield plant-1. Higher values of sca for almost all characters over gca indicated preponderance of non-additive gene action for expression of these characters. Parents, A-8, NA-12 and 35-2 were observed to be the good combiners for a number of characters. The F1 hybrids 651-61-10 x A-4, Assam 5B x A-8 and SPS-1 x A-8 were found promising specific combinations for a number of characters including yield. Either one or both parental lines having high gca effects were involved in the crosses having better sca effects. Preponderance of non-additive gene action for all the characters suggested that heterosis breeding might be effective for the improv~mentof yield and its contributing attributes in chilli.
