A field experiment was conducted from September 2019 to January 2020 (thaladi season) at Pandit Jawaharlal Nehru College of Agriculture and Research Institute, Karaikal, Puducherry to study the effect of cultivars and weed management practices on productivity, profitability and energetics of dry direct-seeded rice (DDSR). The experiment was laid out in a split-plot design (SPD) with 15 treatment combinations and replicated thrice. Cultivars (ADT 46, CO 52 and improved white ponni) were assigned to main plots and 5 weed management practices viz. application of pendimethalin @ 1 kg a.i ha-1 as pre-emergence (PE); bispyribac-sodium @ 0.02 kg a.i ha-1 as post-emergence (POE) at 20 DAS; pendimethalin @ 1 kg a.i ha-1 followed by (fb) bispyribac-sodium @ 0.02 kg a.i ha-1; hand weeding (HW) twice at 20 and 40 DAS and weedy check were assigned to sub-plots. Results have shown that cultivars 'ADT 46' was the most promising cultivar for DDSR situation since it recorded the highest grain yield (3.76 t ha-1), energy use efficiency (4.43), energy productivity (0.3 kg MJ-1), net returns (Rs. 43.74 × 103 ha-1) and benefit: cost ratio (1.52). Among the weed management practices, sequential application of pendimethalin fb bispyribac-sodium found superior over other treatments in terms of grain yield (3.73 t ha-1), energy use efficiency (4.35), energy productivity (0.3 kg MJ-1), net returns (Rs. 42.27× 103 ha-1) and benefit: cost ratio (1.43). Thus, cultivation of 'ADT 46' integrated with sequential application of pendimethalin fb bispyribac-sodium could be recommended for DDSR under coastal deltaic ecosystem of south India.

Background: Intercropping is the more profitable cropping system in Agriculture for marginal hold farmers. In this system risk cover in abiotic stress and farmers have gain one crop mostly who are using herbicide to control weeds. Crops raise fast and with controlled weeds. Scientific approach of intercropping increases the productivity per unit area and per unit time under a situation where two crops are grown in a certain row proportion. The selection of compatible crops is one of the important considerations, in deciding economically viable and feasible intercropping system. Chickpea with mustard is a prominent intercropping system in Indian subcontinent. The majority of the farmers adopt this system under recourse constraint conditions. Since Chickpea is a poor competitor for weeds because of its slow growth and limited leaf area development at early stages of crops growth and establishment.Methods: An experiment was conducted at College of Agriculture Farm Gwalior during Rabi season of 2011-12 and 2012-13. The experiment was laid out in Split-Plot Design with three replications. Eighteen treatment combinations comprising three intercropping systems, viz, chickpea (sole), mustard (sole) and chickpea with mustard were taken as main plot treatments and six weed management practices viz, weedy-check, weed free, fluchloralin@ 1.0kg/ha pre-plant incorporation (PPI), pendimethalin @ 1 kg/ha as pre-emergene, (PE), Isoproturon 0.75 kg/ha as post emergence (POE) and quizalofop -ethyl @50 ml/ha (PoE) as sub plot treatments. The recommended dose of fertilizer in chickpea 18 kg/ha of nitrogen and 46 kg/ha of P2O5 were applied with equal distribution to both the crops through 100 kg /ha diammonium phosphate as basal application at the time of sowing in rows below the seed. A seed rate of 70 kg and 5 kg/ha for chickpea and mustard was used in their sole crops respectively. Result: Chickpea with mustard intercropping system proved to be the most promising system which obtained more net returns and benefit: cost ratio. So for realizing higher net returns and benefit: cost ratio, chickpea with mustard may be recommended to farmers who are interested in taking both the crops instead of their pure stands as it proved to be economically better and feasible in generating more monetary benefits by spending fewer amounts for their better lively hood security as well as land use efficiency.

Analysis of energy flows and economic dynamics allows the diversity of variables involved in the agroecosystem production to be observed in the same dimension. In this way, efficiency and performance can be analysed integrally to identify critical points to be improved. The objective of this study was to analyse the energy-economic efficiency within three management strategies (Management I, Management II and Management III) of the maize agroecosystem in the Frailesca region of Chiapas (Mexico). The hypothesis was that systemic typologies, defined by modes of production, can lead to different efficiencies for the system performance. The study was descriptive; case studies were selected as representative based on their technological variants. The efficiency analysis was conducted using a balance of inputs and outputs expressed in energy and economic terms. Management III resulted in better energy use efficiency, with 6.47, while Management I and Management II were more economically feasible, with a benefit/cost ratio of 1.56 pesos.

Sesame is one of the important oilseed crops in India. The major constraint of its low productivity is non-adoption of improved technologies by the farmers. Cluster Frontline demonstrations to highlight the impact of different improved technologies like method of sowing, nutrient management, weed management and adoption of whole package of practices of improved technologies for the crop were conducted at 125 farmers' fields during Kharif 2017 and 2020 under rainfed conditions. The improved technologies improved the yield attributing traits as well as seed yield of the crop. The improved technology recorded a mean yield of 476 kg/ha which was 44.68% higher than that obtained with farmer's practice yield of 329 kg/ha. Higher mean net returns of 33,363/ha with a benefit: cost ratio of 3.28 was obtained with improved technologies in comparison to farmer's practice (mean net returns of 18,222/ha and benefit: cost ratio of 2.25).

economic analysis of laser land levelling (LLL) in comparison with conventional land levelling (CLL) was exercised by the study. Karnal district was selected purposively only because it was having highest area under paddy-wheat cropping pattern in the state. Different cost concepts were used to analyse economic impact of laser land levelling. As laser land levelling has major impact on irrigation use efficiency that’s why Karnal district was most appropriate for study because it was having major cropping pattern as paddy and wheat which incorporate water thirsty crops. Total cost under laser land levelling was Rs125392 and Rs95037 while under conventional land levelling it was Rs126918 and Rs 98667 for paddy and wheat respectively. Gross returns under LLL were Rs 155480 and Rs 115880 while under CLL they were Rs148228 and 113798 for paddy and wheat respectively. Net Returns under LLL were Rs 30088 and Rs 20843 while under CLL they were Rs 21310 and Rs 15132 for paddy and wheat respectively. Benefit cost ratio under LLL was 1.24 and 1.18 while under CLL it was 1.17 and 1.15 for paddy and wheat respectively. These results shows economic profitability of LLL over CLL and recommended to adopt LLL on wider scale and tap benefits of this resource conservation technology.

A front line demonstration on direct seeded rice was conducted during Kharif season of 2014 and 2015 to enhance the productivity of rice, improving resource use and minimizes the production cost. Frontline demonstration is a medium to make awareness about the technology direct seeded rice (DSR) and popularised amongst farmers. The present study showed that yield attributing characters under DSR was higher compared to farmers practice-puddled transplanted rice (PTR). However, grain yield under PTR was slightly higher (5.1%) than DSR. Economics of rice production technology, favour DSR over farmers practice-puddled transplanted rice (PTR) due to higher net return and a benefit-cost ratio under DSR as compared to transplanting. Direct seeded rice fetches a high net return of Rs. 39,875 with benefit-cost ratio of 2.74, as compared to PTR, attributed by the involvement of high cost for land preparation and nursery raising, transplanting and irrigation under transplanting.

Background: Intercropping is an effective tool to enhance productivity, biodiversity and stability of the fragile agro-ecosystem. In the era of shrinking resources, intercropping based on pulse crops like soybean can play an important role in crop diversification as well as agricultural sustainability. But, the information on soybean based intercropping systems is limited and needs to be explored for north-west India. Methods: A field experiment was conducted during kharif seasons of 2015 and 2016 to evaluate the effect of different soybean based intercropping systems under different planting patterns on productivity, profitability and energetics. Soybean crop was planted as sole as well as in intercropping systems viz., soybean (45 cm) + mung bean (1:1), soybean (45 cm) + cowpea fodder (1:1), soybean (45 cm) + groundnut (1:1), soybean (45 cm) + maize fodder (1:1) , soybean (60 cm) + mash (1:1), soybean (60 cm) + mung bean (1:2), soybean (60 cm) + cowpea fodder (1:2), soybean (60 cm) + groundnut (1:2), soybean (60 cm) + maize fodder (1:2) and soybean (60 cm) + maize (grain) (1:1). Result: The pooled results over two years elucidated that soybean equivalent yield was affected significantly by different intercropping systems. Soybean (45 cm) + groundnut (1:1) produced the highest soybean equivalent yield and it was significantly better than all other systems except soybean (60 cm) + groundnut in 1:2 row ratio. Similar trend was followed by production efficiency. Both, soybean (45 cm) + groundnut (1:1) and soybean (60cm) + groundnut (1:2) systems produced significantly higher energy productivity as compared to sole soybean. The highest gross (Rs. 98185 /ha) and net returns (Rs. 56122/ha) were obtained in soybean (45 cm) + groundnut (1:1) intercropping system whereas the highest benefit cost ratio was obtained in soybean (60 cm) + maize fodder (1:2) system.

A study was conducted for two consecutive years to determine the yield and system productivity of two cropping patterns viz. IP: (Wheat - Jute - T. aman) improved pattern with improved management practices and FP: (Fallow - Fallow - T. aman) farmers’ pattern with farmers’ management practices in char (adjacent to the river) area of Netrakona region of Bangladesh. The experimentswere laid out in a randomized complete block design with 10 dispersed replications at a farmer’s field. The two years mean data showed that the total component crops of IP (wheat-jute-T. aman rice) gave higher yield as well as a by-product in both years. The higherrice equivalent yield (10.52 and 10.63 tha-1), production efficiency (30.13 and 30.43 kg ha-1 day-1) land-use efficiency (87.13 and 87.84%)and benefit cost ratio (2.15 and 2.11) pointed out the dominance of the improvedpattern over the farmer’s existing pattern. Higher rice equivalentyield signified that improved cropping pattern (Wheat - Jute -T. aman) could be appropriate in Netrakona region for rising crop productivity andcropping intensity.The higher production efficiency, land use efficiency and benefit cost ratio indicated the superiority of the improved pattern over the farmers’ practices.It can be concluded that farmers of the char area of the Netrakona region might follow wheat (var. BARI Gom-26) - jute (var. O-9897) - T. aman (var. BRRI dhan49) cropping system in char land for higher productivity and profitability.

The research was conducted at Beltari Sandhikharka-10, Arghakhanchi district to study about the effect of various doses of boron on growth and yield attributing characters of cauliflower (Brassica oleracea var. botrytis) during off-season from February to June in 2020. Five treatments; B0 (control/no application), B1: 2kg/ha, B2: 4kg/ha, B3: 6kg/ha, B4: 8kg/ha which are the different doses of boron application were laid out in Randomized Complete Block Design (RCBD) with 4 replications. The growth parameters like plant height, number of leaves per plant leaf length and leaf breadth of largest leaf were recorded multiple times with 15 days interval. Days to curd initiation and Days from curd initiation to harvest were recorded by regular field observation. The yield parameters; curd weight with leaves, Marketable curd weight, average curd yield, incidence of hollowing were recorded during harvest. The economics from application of boron doses in cauliflower production was obtained in terms of cost of cultivation, gross returns, net returns, and benefit cost ratio. The result showed that the growth and yield attributing characters of cauliflower were significantly affected by application of boron in which the value of these parameters was found significantly higher in B1 followed by other treatments. The average curd yield of cauliflower in B1 was found to be 12.39 mt/ha which was 48.92% higher than that of B0 with curd yield 8.32 mt/ha. Similarly, the net return was found significantly the highest in B1 and the lowest in B0. The result showed that application of boron in the range of 2-4 kg/ha is preferred to control and higher doses in respect of both productivity and economics.
