A four crops-based trial was conducted for the two consecutive years at MLT site Raniganj, Sadar, Dinajpur and Kashiatola, Ghoraghat, Dinajpur during 2015-16 and 2016-17 to develop a sustainable and economically profitable cropping pattern Potato-Boro-T. Aus-T. Aman against the farmers existing pattern Fallow-Boro-Fallow-T.Aman. The experiment was carried out in RCB design with six dispersed replications. Suitable and short duration high yield potential varieties of different crops Potato ((BARI Alu-7), Boro (BRRRI dhan28) T.Aus (BRRI dhan48) and T.Aman (BRRI dhan62) were selected for the experiment. Grain yield of rice and potato tuber yield was satisfactory. Inclusion of two crops (Potato and T. Aus rice) in the existing pattern attributed to the higher system productivity. The improved alternate cropping pattern produced the higher gross return and gross margin compared to the farmers existing pattern. The marginal benefit cost ratio (MBCR) over the existing pattern was 2.01 at Ghoraghat and 1.85 at Raniganj which indicated the superiority of the alternate pattern over the farmer’s practice. Potato based cropping pattern could be most suitable and profitable pattern in these areas. From the two years observations in both the locations, four crops pattern could be recommended for higher system productivity and economic benefit along with for more employment opportunity.

This research work was conducted to determine the Morphometric diversity of Callosobruchus maculatus in six Local Government areas of Kwara State, (Ifelodun, Irepodun, Asa, Ilorin West, Ilorin East and Ilorin South). Three (3) markets were surveyed in each of the six (6) local government areas and one measure of infested cowpea with Callosobruchus maculatus (Bean weevil) was obtained in each market. Five (5) bean weevils (Callosobruchus maculatus) from each of the three locations (market) were kept in different transparent containers containing ethanol solution and labeled (for the different location at which they were obtained). The samples were taken to the insect laboratory (insect museum) of the Department of Crop Protection, Faculty of Agriculture Ahmadu Bello University (ABU), Zaria, Kaduna state for classification. The data were subjected to Analysis of Variance (ANOVA) using statistical package version 9.0 and mean were separated using Duncan Multiple Range Test (DMRT) at 5 % probability. The result obtained showed that Asa and Ilorin South had the largest diversification of Callosobruchus maculatus and only Callosobruchus maculatus was identified in all the six (6) selected Local Government Areas of Kwara State.

One of the advancements in Agriculture in recent time is the boost of crop yield to increase the number of output and feed the growing Nigerian population. The higher the output the less cost of food items and the more the food security. Kano State is one of the focal point not only on rain fed Agriculture alone but in irrigation farming. Irrigation was adopted coupled with soil fertility. most major crops such as Sorghum Bicolor, Maize, Millet, Beans and Groundnuts are typically grown during rainy season, while market garden crops such as Tomatoes, Pepper, Onion and Rice are now cultivated during the dry period in large hectares of land. This study focuses on different crops yield and its spatial distribution; to calculate the total crop yield per hectare and ascertain the duration of bumper harvest using trend analysis and normal probability. The result indicated more turn-out of farmers with double output of both rain fed and irrigation crops from 2019 and 2020 in two major local government area of Kano State Nigeria

The research was conducted with 12 cherry tomato genotypes at Regional Research Station, Bangladesh Institute of Research and Training on Applied Nutrition (BIRTAN), Noakhali, Bangladesh during the year 2020-21 to select suitable cherry type tomato for processing purposes. Among the genotypes, highest number of fruits per cluster was observed in CT-11 (31.67), higher average fruit weight (69.53g) and the number of locules (5.67) per fruit was recorded in CT-14 but the highest fruit yielder was CT-15 (11.30 kg). Higher heritability, genetic advance, genotypic coefficient of variation for number of fruits and clusters per plant, fruits per cluster, fruit yield per plant were controlled by additive gene action, which indicates the scope for improvement of this characters. A significant positive correlation coefficient was observed with plant height, the number of clusters per pant, fruits per plant and pericarp thickness. Yield showed a significant linear regression coefficient with number of clusters per plant, fruits per cluster, fruits per plant, fruit length and fruit diameter. Principal component and cluster analyses revealed that four principal components accounted for 90.60% of the morphological variability of the genotypes evaluated. Among the genotypes, CT-5 produced the highest number of fruits per plant and CT-15 produced the highest fruit yield and can be selected for cultivation under Bangladesh conditions.

Because of its relevance in health, pharmaceuticals, spices, and income-earning, nigella is now used all over the world. This crop is grown all over the world. Even though nigella is essential, the yield and productivity per hectare in Nepal in comparison to other countries is quite low. The lack of better variety, lack of fertilizer management, lack of knowledge of cultural methods, and illnesses and insect pest management are all blamed for the lower yield. By examining such issues, a solution for nigella’s low productivity can be devised. As a result to address such problems a review is done on fertilizer requirements, the adaptation of available cultivars, agronomic practice recommendations, disease, and insect pest management, and other topics that are beneficial from the farmer’s point of view.

Urtica dioica is the flowering herbaceous perennial plant of family Urticaceae distributed globally but commonly considered as a weed in agricultural production. Stinging nettle is one of the emerging plant which has number of medicinal, curative value along with serving as the food and nutritional value in the house of people living below the poverty line. Despite of its million benefit it does not gain much popularity as it deserve. In agricultural production it is considered as weed so removed from the main field. However if the plant is planted in collaboration with other plants it fulfill both nutritive value and serve the main plant with low infestation of disease as pest as stinging nettle avoid the closeness of insect pest as it consist of thorn and also possess host plant resistance characteristics. The plant is only famous in the local rural level and still number of research is to be carried out to transform the globally distributed weed to marketable plant so as to finalize its medicinal value.

In Nepal, rice is the major staple food crop and is ranked first as a cultivated crop. Nitrogen is one of the most important factors limiting its yield. There has been an overuse of nitrogen fertilizer in rice fields resulting in low N use efficiency and high loss of nitrogen. A field experiment was carried out on acidic sandy loam soil of the Directorate of Agricultural Research, Gandaki, Lumle, from June to November 2016 and 2017 to evaluate the performance of cold-tolerant rice (Lumle-2) and nutrient use efficiency as affected by various levels of nitrogen application. The experiment was laid out in a randomized complete block design with five different level of nitrogen as treatments (0, 50, 100, 130, 150 Kg N ha-1) and replicated four times. Phosphorus, potassium and FYM were applied at the recommended dose. A significantly marked increment in grain yield was noticed in both years as the nitrogen level increases up to 130 Kg N ha-1. However, when the nitrogen dose exceeded 130 Kg N ha-1 have decreasing effect in grain yield, straw yield and NUE. The productivity (4.35 t ha-1) and NUE of cold tolerant rice (Lumle-2) can be improved significantly by applying an optimum level of N fertilizer up to 130 Kg N ha-1.
在尼泊尔，水稻是主要的粮食作物，在种植作物中排名第一。氮是限制其产量的最重要因素之一。稻田过度施用氮肥，导致氮素利用效率低，氮素流失严重。2016年6月至11月和2017年11月，在隆米县甘达基农业研究局酸性砂质壤土上进行了田间试验，以评价不同施氮水平对耐寒水稻(Lumle-2)性能和养分利用效率的影响。试验采用完全随机区组设计，5个不同氮水平(0、50、100、130、150 Kg N hm -1)处理，重复4次。磷、钾和FYM按推荐剂量施用。当施氮量增加到130 Kg N hm -1时，籽粒产量均有显著增加。但当施氮量超过130 Kg N ha-1时，籽粒产量、秸秆产量和氮肥利用效率均呈下降趋势。以130 Kg N hm -1为最佳施氮量，可显著提高耐寒水稻(Lumle-2)的产量(4.35 t hm -1)和氮素利用效率。

The infestation of insect pests has a significant impact on cabbage yield. Lepidopteran insects are one of the most important insect pests in the reduction of cabbage output. The present study aimed to evaluate some biopesticides used against major cabbage insect pests. The experiment was set up in a Randomized Complete Block Design (RCBD) with three replications. There were seven treatments used: T1 (Abamectin 1.2EC @ 1 ml/L of water); T2 (Azadirachtin 1EC @ 1 ml/L of water); T3 (Potassium salt of fatty acid @ 1 ml/L of water); T4 (Spinosad 45SC @ 1 ml/L of water); T5 (Bacillus thuringiensis @ 1 ml/L of water); T6 (Abamectin + Bacillus thuringiensis @ 1 ml/L of water) and T7 (untreated control). All of the treatments were given seven days apart. T4 that reduced the highest incidence over control of cabbage caterpillar and diamondback moth larvae (50.33 % and 51.90 %, respectively) had the lowest mean incidence of cabbage caterpillar (6.82 larvae/5 plants) and diamondback moth larvae (4.87 larvae/5 plants), whereas the untreated control treatment (T7) had the highest values of all these parameters. T4 had the lowest cabbage head infestation (21.37 %) and the maximum cabbage yield (36.40 t/ha), followed by T1 (34.07 t/ha). According to the results of the study, treatment T4 (Spinosad 45SC @ 1 ml/L of water at 7-day intervals) had the best performance of all the treatments tested.

An experiment was conducted in IAAS to study the effectiveness of different priming methods on germination & seedling characters of Marpha Chauda Pate variety of broadleaf mustard. The experiment was laid in CRD with 6 treatments each replicated 5 times. Treatments used were GAȝ (100 ppm), PEG (10%), NaCl (2%), Mannitol (4%), controlled, and hydro-priming. The highest germination percentage was 91.2% with GAȝ & PEG priming while the lowest germination was achieved at 77.6% from NaCl. Lower germination in NaCl might be due to the toxic effect of salinity. Hydro-priming gave the highest fresh weight. Unprimed seeds gave the highest fresh weight (0.338 gm). The highest vigor index (1032.74) was achieved with PEG. Highest R: P. ratio was recorded with hydro priming and lowest with GA3. Overall, priming with PEG (10%) gave better performance. Priming with PEG would be beneficial for germination and seedling establishment of mustard.
