Cauliflower is one the important vegetable crop in the tropics; the curd contains high fibres, potassium, carotene and vitamin C. However, the production and productivity of cauliflower in Indonesia has been low and cannot meet the demand, resulting in high importation of cauliflowers into Indonesia. Bogor Agricultural University has developed potential lowland cauliflower genotypes, BOB017 and BOB020, with higher productivity. In this study, we evaluated three fertigation methods on the growth, yield and economic returns of the two lowland cauliflower genotypes.  The experiment was arranged in a split-plot design with four replications. The main plot contained two cauliflower genotypes, BOB017 and BOB020. The subplot was three fertilizer application methods: through drip irrigation, soil drench, and drilled. The results showed that BOB020 had an earlier harvest time (60 days) compared to BOB017 (71 days). The soil drench fertigation method showed the highest curd weight (351.64 g), curd diameter (14.65 cm) and yield (12.39 t.ha-1) compared to the other two fertigation methods. The BOB017 genotype fertilized with soil drench method resulted in the highest B/C ratio (3.32). The study concluded that growing cauliflower using the soil drench method resulted in the optimum growth of cauliflower, high yield and net income.

The SSNM is need-based feeding of crops with nutrients in right source, right rate, right time and right place while, recognizing the inherent spatial variability which enhances crop productivity, profitability, NUE and avoids nutrient wastage. This paper deals with the SSNM technologies approaches and tools which are able to enhance NUE, crop productivity and profitability in wheat crop. The SSNM caters to help in improving NUE as it provides an approach for feeding crops like rice, maize and wheat, etc with nutrients as and when needed. It is based on the concept when and how much to feed. The main benefit for farmers from improved nutrient management strategy is an increase in the profitability and reducing the cost and environmental threats. The SSNM reduces the wastage of fertilizers by preventing excessive use of fertilizers and avoiding fertilizer application when the crop does not require nutrient inputs. It also assures that N, P and K are applied in that ratio required by the intended crop. It aims to achieve high yield and high efficiency of nutrient use, leading to high cash value of the harvest per unit of fertilizer invested. Results from three years data from 2014 to 2016, 173 on-farm sites in four districts of Bihar showed that NE significantly increased wheat yields and economic returns compared to the generalized Farmers’ Fertilization Practice (FFP). NE’s impact on fertilizer use in wheat shifted K application upwards while also minute upwards N and P application rates. The study used recent advances in information and communication technology (ICT) and computer based application of "Nutrient Expert for Wheat, Maize and Rice", which transform the science of SSNM into guidelines matching the field-specific needs and conditions of a farmer. Across all sites, NE wheat increased to yield and economic benefit (i.e. gross return above fertilizer costs) over FFP. Recommendations from NE wheat also increased yield (by .63 t/ha) over FFP with large increase in fertilizer K (+50.88 kg K20/ha) and N and P fertilizer was minute increase N (+ 4.32 Kg N/ha) and P (+ 6.21 Kg P2o5/ha). Result revealed that nutrient expert application significantly increase higher grain yields over farmer fertilizer practice (FFP). Average wheat grain yield in NE practice was 45.32 Kg ha-1, which was 13.9% more than the Farmer Fertilizer Practices, with NE recorded an additional net income of Rs.8434 ha-1 over FFP respectively.

<p>True shallot seed (<em>Allium cepa var Aggregatum group</em>) is an alternative way of growing shallot. Different environments and cultivars need a specific study. The aim of this research was to find out the best technology to grow Trisula true shallot seed by managing plant densities and applying compost and biofertilizer in alluvial soils. The study was performed from May to October 2015, using a split-plot design with four replications. The main plot was plant density: 100 plants m-2 and 70 plants m-2. Subplots were five fertilizer application combinations, they were 100% recommended dose of NPK (R-NPK), 100% R-NPK + compost, 100% R-NPK + compost + biofertilizer, 50% R-NPK + compost and 50% R-NPK + compost + biofertilizer. Results showed that biomass and bulb yield were significantly affected by plant density and fertilizer application. The reduced 50% R-NPK by substituting with compost and biofertilizer was unable to maintain shallot bulb yield equal to 100% R-NPK, suggesting insufficient nutrients derived from compost to satisfy the shallot requirement. The best technology to grow true shallot seed of Trisula variety was 100 plants m-2 plant density and 100% NPK (consisting of 180 kg N ha-1, 52 kg P ha-1 and 50 kg K ha-1) with 2.5 t ha-1 compost that achieved the highest bulb yield of 9.83 t ha-1 and increased the revenue.</p>

Field experiment was conducted at Instructional Farm, Jaguli (Mohanpur), Bidhan Chandra Krishi Viswavidyalaya, West Bengal, India during two consecutive summer seasons of 2010-11, and 2011-12. The experiment was laid out in split-plot design having 4 levels of irrigation– rainfed without mulch, rainfed with mulch, irrigation at IW (depth of irrigation water) / CPE (Cumulative pan evaporation) ratios of 0.5 and 0.75 in main-plot and 4 inter cropping systems, sole maize, sole mungbean, maize + mungbean (1:1 row ratio) and maize + mungbean (3:2 row ratio) considered as sub-plot treatments replicated thrice. Results revealed that application of irrigation and intercropping systems markedly influenced the growth, yield and yield components (number of cobs/plant, number of grains/cob in case of maize and number of pods/plant and number of seeds/pod in case of mungbean) where the maximum value of these components were recorded with the application of irrigation at IW/CPE ratio 0.75 in sole crop. Maize-mungbean in 3:2 row ratio yielded higher than that of 1:1 intercropping system which might be due to less light interception and more competition for water and nutrition between both the crops. CU of water increased with the increasing levels of irrigation and the maximum value (17.75 kg ha-1 mm- 1) of WUE (water use efficiency) was observed with irrigation at IW: CPE ratio 0.75 under intercropping system of maize : mungbean in 3:2 row ratio followed by IW: CPE ratio 0.50. Among the sole crop, maximum WUE was with IW/CPE ratio 0.75 might be due to more consumption of water corresponding to production potential of maize, while, it was more under rainfed with mulch in mungbean. The relative crowding coefficient (RCC) also revealed both the intercropping systems were advantageous and the land equivalent ratio (LER) increased with the level of irrigation.Thus, maize grown in association with mungbean (3:2 row ratio) were found to be more profitable (B:C ratio of 2.58) with higher monetary advantage as compared to sole crop of maize (B:C ratio of 1.98) with the application of irrigation at IW: CPE ratio of 0.75 in new alluvial zone of West Bengal.SAARC J.

<p>Soils of the southern Guinea savanna zone of Nigeria are inherently infertile due to shortened fallow period and the continuous use of inorganic fertilizer which depletes the soil of micronutrients such as zinc over time. A field trial was carried out at the Teaching and Research Farm of the University of Ilorin, Nigeria during the 2016 and 2017 cropping seasons to evaluate the effect of zinc and NPK fertilizer on the growth, yield and zinc concentration of seeds of sesame. The experiment was laid out as a factorial fitted into a randomized complete block design (RCBD), replicated thrice. The treatment consisted of four levels of ZnSO<sub>4</sub> (0, 5, 10 and 15 kg ha<sup>-1</sup>) and four levels of NPK 15:15:15 (0, 100, 200 and 300 kg ha<sup>-1</sup>). Data collected were subjected to analysis of variance (ANOVA) and means were separated using new Duncan multiple range test at 5 % level of probability. Results obtained showed significant effects of Zn and NPK rates on plant height, number of leaves, yield per plot and yield per hectare. The application of 15 kg ha<sup>-1</sup> Zn and 300 kg ha<sup>-1</sup> (15:15:15) NPK resulted in high yield and high zinc content of seeds.</p>

Fertilizer application was done twice a year, while mycorrhiza were given once a year toward the end of the rainy season. The plant material used was PB 260 clone, with a standard agricultural practices such as weeding and watering during the dry season. Variables measured were plant height and girth. The results showed that application of 25% extra from the recommended dosage + mycorrhiza was able to accelerate the growth of young rubber plants. Fertilizer dose of 125% from the recommendation + mycorrhiza applied on 2-year-old plants exhibited the same growth with 3-year-old plant that treated with recommended dosage. This result indicates that mycorrhiza works synergistically with inorganic fertilizer, which enhances the effectivity and efficiency of extra fertilization in gradually rejuvenation models.</em></p>
