Present study was conducted during Summer and Kharif 2020 across villages of Gaya district under the South Alluvial zone of Bihar to assess the usefulness of Agro-met Advisory Services (AAS) and to quantify the economic gain of farmers through adoption of advisory in their day-to-day farming practices. To achieve this, two groups of farmers were formed namely, a group adopting the agro-met advisories (AAS farmers) and other group not aware of agro-met advisories (non-AAS farmers). A total of 80 farmers (including AAS and Non AAS) were identified. The agro-met advisory were circulated among AAS farmers for Summer and Kharif season of 2020 and care was taken for proper implementation of advisories by this group. Expenditure incurred & crop situation of both the group of farmers were compared at every stage from land preparation to harvest and crop growth and yields were monitored regularly among them. Significant results were reported for crop growth and yield among the AAS farmers compared to non-AAS. AAS farmers have obtained a net income of Rs. 45188 and Rs. 37273 while, non AAS farmers obtained a net income of Rs. 26225 and Rs. 28510 for green gram and rice respectively. The AAS farmers reported 41.96 and 23.5 per cent of additional benefit in green gram and rice, respectively. The gain in additional benefit was due to management of crop according to agro-met advisory bulletins. Therefore, adoption of agro-met advisory bulletin based on past, current and future weather forecast is an effective tool for enhancing the net productivity and income.

A field experiment was undertaken to study the effect of different liquid manure on growth and yield of green gram during summer seasons of 2015 and 2016. The experiment was conducted at Model Organic Farm at Kalyani C block of Bidhan Chandra Krishi Viswavidyalaya Nadia under New alluvial zone of West Bengal with 8 different treatments of liquid manure i.e. (T1 = Jivamrut+FYM, T2 = Sanjivak+FYM, T3 = Panchagavya+FYM, T4 = Cow urine+FYM, T5 = Vermiwash+Cow urine + FYM, T6 = Vermiwash+FYM, T7 = Vermicompost+FYM, T8 = Control) and with three replications. The result of experiment revealed that the combined application of Panchagavya @8 kg N equivalent along with FYM @ 12 kg N equivalent (T3) exerted significant influence towards higher growth parameters like plant height, LAI and dry matter accumulation throughout the crop growth period, yield attributes like number of pod/plant, pod length, number of seeds/pod and test weight and thus achieved maximum grain yield (1085 kg/ha) and stover yield (3224 kg/ha). On the basis of field performance, it may be inferred that the treatment FYM@12 kg N equivalent at land preparation + Panchgavya @8 kg N equivalent (twice equal split applications at 30 DAS and 45 DAS through irrigation water) may be recommended as a better organic package of greengram followed by FYM @12 kg N equivalent at land preparation + vermicompost @8 kg N equivalent (twice equal split applications at 30 DAS and 45 DAS as top dressing) among all other treatments applied in the soil.

Many see organic agriculture as the most sustainable form of farming and as the paradigm for global food production in the future. One of the solutions to food insecurity and malnutrition in Sub-Saharan Africa is to promote local crops, encourage the use of locally source materials as amendment, improve their traditional system of production, and so diversify subsistence crop. The major reasons are the lack of knowledge and skill in land preparation and agronomic practices, weather uncertainties, pest outbreak and above all the use of fertilizer. Hence, this research will be carried out to investigate the effects of integrated application of Urea fertilizer and Goat Manure on soil Nutrient Availability and Okra performance. Field trials were conducted with four treatments replicated three times in a Randomized Complete Block Design (RCBD). The treatments were Control (no Urea, no goat manure), 8t/ha-1 goat manure + 200kg/ha-1 urea fertilizer; 8t/ha-1 goat manure + 175kg/ha-1 urea fertilizer and 8t/ha-1 goat manure + 150kg/ha-1 urea fertilizer. Treatments were applied three weeks after planting by ring method with Urea and goat manure mixed. Soil physical and chemical properties, growth and yield parameters were evaluated. Data were analyzed using Analysis of Variance (ANOVA) and Duncan Multiple Range. 8t/ha-1 goat manure + 200kg/ha-1 urea fertilizer gave the highest plant height, leaf area as well as number of leaves than other treatment. However, the fruits weight, days of 50% flowering, number of fruit, fruits diameter and fruits length were significantly increased at 8t/ha-1 goat manure + 200kg/ha-1 urea fertilizer.

The relationships between the actual amount of spring-applied trifluralin detected in soil at seeding, initial injury to flax, and crop growth and yield were investigated in southern Manitoba over three growing seasons. As the amount of trifluralin in the soil increased, flax density and dry matter production decreased, such that at a soil concentration equivalent to 1 kg ai ha−1trifluralin, the two were reduced by 40 and 49%, respectively. Recovery from early-season injury was characterized by enhanced crop growth rates (CGRs) and net assimilation rates (NARs) of surviving plants during the remainder of the growing season. Maximum recovery occurred in plots where trifluralin levels in the soil were between 0.8 and 1 kg ha−1at seeding. During the interval between stem elongation and bud initiation, CGRs and NARs of flax in the trifluralin-treated plots exceeded those of flax in the untreated plots by up to 1.5 and 1.2 times, respectively. Additionally, the number of branches per plant increased linearly as trifluralin amounts in the soil increased. Flax seed yield was decreased by trifluralin as described by the equation: flax seed (% of untreated control) = 104.9 - 13.3[trifluralin detected (kg ha−1) at seeding]. Based on this equation, trifluralin levels in the soil of up to 0.7 kg ai ha−1caused less than a 5% reduction in flax yield under weed-free conditions.

An experiment was conducted at Sadipur charland under Farming System Research and Development Site, Hatgobindapur, Faridpur, during rabi season of 2012-13 and 2013-14 to study the growth and yield performance of cv. BARI Gom-24 as affected by different dates of sowing under Agro-ecological Zone-12 (AEZ-12) of Bangladesh. The experiment was laid out in randomized complete block design with six replications, comprising five different dates of sowing viz. November 5, November 15, November 25, December 5 and December 15. Results reveal that the tallest plant, leaf area index, total dry matter, and crop growth rate were observed in November 25 sown crop and leaf area index, total dry matter and crop growth rate were higher at booting, grain filling, and tillering stages of the crop. Maximum effective tillers hill-1 (3.49), spikes m-2, (311), number of grains spike-1 (42.20) and 1000-grain weight (52.10 g) were produced by November 25 sown crop exhibited the highest grain (4.30 t ha-1) and straw yield (4.94 t ha-1) as well as harvest index (46.88%) of the crop. Lowest performance was observed both in early (November 5) and late sown crop (December 15). The overall results indicated that November 25 sown crop showed better performance in respect of growth and yield of wheat under charland ecosystem of Bangladesh.J. Bangladesh Agril.

Weed problem appears to be the most deleterious factor causing between 25 and 60% reduction in potential yield of cowpea. Field trials were therefore conducted to study the effect of inter-row spacing and period of weed interference on growth and yield of cowpea (Vigna unguiculata (L) Walp) at the Teaching and Research Farm of the Federal University of Agriculture, Abeokuta (07° 15'; 03° 25' E) in South Western Nigeria during the early and late wet seasons of 2009. The experiment consisted of eight main plots of weed interference which included initial weed removal for 3, 6, 9, and 12 weeks after sowing (WAS) and subsequently weed –infested until harvest as well as initial weed infestation for corresponding periods and thereafter kept weed free until harvest. There were also sub-plot treatments of three inter-row spacing of 60, 75, and 90 cm. All treatments in different combinations were laid out in a split-plot design with three replications. In both trials, the use of inter-row spacing of 60 cm resulted in significant reduction in weed growth as evident in lower weed dry matter production and subsequent higher cowpea pod and grain yields than those of 75 and 90 cm inter-row spacing. Initial weed infestation of up to 3 WAS did not have any adverse effect on crop growth and cowpea grain yields provided the weeds were subsequently removed. On the other hand, cowpea grain yield loss was not significantly averted by keeping the crop weed free for only 3 WAS without subsequent weed removal. In this study, initial weed-infestation for 6 WAS and beyond significantly depressed various crop growth parameter and cowpea grain yield compared with the crop kept weed free throughout its life cycle. In order to obtain optimum yields similar to that of the weed free cowpea field, it was required to keep the crop weed free for 6 WAS and beyond. However, frequent weeding beyond 9 weeks after sowing did not improve cowpea yield significantly and as a matter of fact it may even result in reduction of cowpea grain yield due to mechanical damage of hoe weeding. The practical implication of this finding is that early weeding starting from 3 WAS is very crucial for cowpea production while the critical period of weed removal for optimum yield in cowpea is between 3 and 9 WAS in the forest-savannah transitional zone of south Western Nigeria.

A field experiment was conducted during the summer, 2014 at College of Agriculture, Vellayani, Kerala to evaluate the influence of irrigation levels, nitrogen stress and method of application of fertilizers on growth and yield of yard long bean. The experiment consisted of four levels of irrigation, two levels of nitrogen and two methods of application. The results indicated that daily irrigation at 10 mm depth and recommended dose of nitrogen (30 kg ha-1) recorded superior values for growth parameters viz., functional leaves per plant and leaf area index The major yield attributes like number of pods per plant and pod yield per plant and total pod yield were not influenced by levels of irrigation and nitrogen indicating that irrigation once in three days at 20 mm depth and nitrogen level of 22.5 kg ha-1 is sufficient for yard long bean. Soil and foliar application of nitrogen and potassium recorded superior growth characters, however, the yield was superior when the recommended dose of nutrients were supplied as soil application. Increasing irrigation interval to three days and imparting N stress did not result in any reduction in gross income and net income while, a higher benefit: cost ratio was noted in irrigation at wider intervals. Soil application of nutrients recorded higher gross income, net income and BCR compared to soil + foliar application.

The experiment was conducted to determine the growth and yield response of pak choi (Brasiccarapa var. Chinkang Genghis Khan) to different foliar fertilizers (viz. vermitea, commercial foliar fertilizer, effective microorganisms [EM-1] and natural farming inputs [NFI]) under protected cultivation. It aimed to evaluate the influence of the different foliar fertilizers on pak choi in terms of growth characteristics, yield components, and pests and disease incidence. Similarly, to conclude which among the foliar fertilizers evaluated will be most the economical for pak choi production. The study was done in the DA-ATI IV-A and LSPU Organic Agriculture Learning Site in the Laguna State Polytechnic University, Siniloan, Laguna in December 2015 to February 2016. A total of 300 plants were used as experimental units in the study. Every treatment was replicated three times and each replication has 10 polyethylene bags planted with two plants each. Data was collected and analysed with the use of the Duncans Multiple Range Test (DMRT). Results revealed that the foliar fertilizers used have no remarkable effect on the weekly height, weekly growth rate, length of leaves, and shoot root ratio of pak choi. Nevertheless, commercial fertilizer significantly increased the mean number of leaves (7.53cm), width of leaves (15.10cm), economic and biological yields (105.10 grams and 106.88 grams, respectively) of pak choi compared with the rest of the treatments, except for vermitea which produced a comparable width of leaves (15.04cm). Also, a significantly lower number of the damaged leaves caused by looper (TrichoplusianiHübner) was noted on plants treated with commercial foliar fertilizer (0.51 leaf per plant). The highest net income was obtained by commercial foliar fertilizer-treated plants, but plants treated with vermitea earned the highest return of investment (ROI). Therefore, the utilization of vermitea in pak choi production can reduce the cost of fertilizer and contribute to an economical production system under protected cultivation.
