Appropriate time of planting and use of suitable sources of nitrogen are highly conducive for better growth and yield of cauliflower. A field experiment was conducted to study the effect of planting dates and sources of nitrogen on growth & yield of cauliflower at horticulture research block of Agriculture and Forestry University, Rampur, Chitwan, Nepal from 1st Nov 2019 to 4th March 2020 using ‘Snow mystic’, a late season variety of cauliflower. The study was laid out in split-plot design with two dates of planting (Dec 1st & Dec 16th) as main plot factors & four sources of nitrogen viz. 100% biochar (BCH), 100% Urea(U), 50% urea+ 50% Poultry manure (U+PM) & 50% Biochar+ 50% poultry manure (BCH+PM) against a control as sub-plot factors and were replicated thrice with 30 experimental units each of 9 m2 size containing 5 rows with 5 plants per row. The recommended dose of fertilizer used for the research was 108:92:60 kg N, P2O5, K2O ha-1 and P and K were supplied through SSP and MOP. The soil of experimental plot was sandy loam with slightly acidic with pH (5.6). The data regarding days to 90% curding, canopy area (cm2), leaf number per plant, above ground dry mater (g m-2) (AGDM), curd size (cm2) and curd weight per plant(g), days to curding to harvesting interval, yield, HI and B:C ratio were recorded and analysed using MS Excel and R studio. Significantly higher number of leaves per plant (16.03), bigger average canopy area (5089.93 cm2), higher AGDM (217.91 g m-2), bigger (1563.03 cm2) and heavier curds (1412.44 g) were recorded in 1st Dec. transplanted cauliflower with significantly higher harvest index (68.20). Regarding the sources of nitrogen, all the above parameters were seen better under BCH+ PM but were statistically at par with other nitrogen sources except control. The 1st Dec. planted crop had 4 more days of curding to harvesting interval than 16th Dec. planted one but the difference was not significant. December 1st planted cauliflower yielded 110% more yield and net returns than 16th Dec. planted crop whereas BCH incurred maximum cost (NRs 322145 ha-1) and U and U+PM were the most profitable in terms of B:C ratio (12.77 and 12.96 respectively).Hence, better crop yield and benefit could be obtained by planting the late season cauliflower (var. Snow mystic) at 1st Dec with the use of 100% urea or U+PM as nitrogen source in plains of Nepal having Chitwan like climate.

The production of rice is least in Pakistan and quite low as compared with other countries. Proper crop management techniques such as intercropping and combining organic manures are useful for better productivity and eco-friendly environment. Whereas studies are needed to evaluate the efficiency of intercrops and incorporation of certain nutrients with these plants. To examine results of intercropping experiment was carried out research by combining nutrient management practices. Five methods were taken including, sole rice, sole Green gram, rice + Green gram (drill), rice + green gram (Ridges), rice + green gram (bed) in the main plot moreover sub-plot included treatments of organic and inorganic supplement. The results show that sole rice followed by intercropping rice along green gram (poultry manure) has better characteristics of growth and yield, higher yield.by changing irrigation methods and farming methods, managing organic additives and fertilizer inputs, and choosing appropriate varieties and planting methods.CH4 decreased by 75% and N2O increased by 58%. The overall rice production of Rice + green gram(ridges) is 2285 kg ha−1 followed by rice + green gram(drill) (2060 kg ha−1). Rice + green gram(ridges) intercropping and (25 percent Urea+25 percent FYM+ 50 percent PM) were also correlated with better N usage performance and post-harvest soil usable N, phosphorus (P) and potassium (K) Benefit: cost (BC) ratios were also higher in the same treatment. From these results it is obvious that the integration of intercropping and induction of organic manures has a substantial impact on the outcome of rice.

For the quantitative evaluation of the efficacy of Nitrogen through different plant nutrient sources in the growth and yield of radish, the field experiment was conducted from March 2020 to June 2020 in an Inceptisol with sandy loam soil of the research field of G. P. Koirala College of Agriculture and Research Centre, Gothgaun, Morang, Nepal. The experiment was carried out in a Randomized Complete Block Design with eight treatments (Biogas Byproduct, Poultry Manure, Goat Manure, Farmyard Manure, Vermicompost, Packaged Organic Manure, Recommended Dose of Chemical Fertilizer, and Control) and four replications. Forty Day (released in 1994 AD) variety of radish was used as a test crop. The recommended 100 kg N per hectare was supplied from each treatment, calculated based on the nitrogen content of each nutrient source. Results showed that there was a significant difference in almost all studied parameters from all treatments over control (P≤ 0.05). The highest total fresh biomass yield (123.415 Mt/ha) and highest delta fresh shoot yield (22.806 Mt/ha) were recorded from the application of a recommended dose of fertilizer, and the highest delta fresh root yield (30.127 Mt/ha) was obtained from the application of FYM. The experiment suggests that the application of FYM significantly increased root yield and was positively correlated with other parameters, which might be a good alternative for chemical fertilizers.

A field experiment was conducted in an Inceptisols with sandy loam soil of the research farm of Agriculture and Forestry University, Rampur, Chitwan, Nepal from October 2016 to January 2017 to evaluate the effects of different sources of organic manure in growth and yield of radish. The experiment was carried out in a Randomized Complete Block Design with six treatments (Poultry manure, goat manure, FYM, biogas byproduct, recommended dose of fertilizer and control) and was replicated four times. Pyuthane Red variety (released on 1994) of radish was used as a test crop. After analysis of primary nutrients of the organic manures, the amount was fixed on the basis of recommended nitrogen (100 kg N per hectare) as a reference value. The application of organic manures significantly increased the plant height, number of leaves, leaf breadth, root length, root diameter and biomass yield. The highest biomass yield (75.16 Mg/ha) and highest root yield (49.41 Mg/ha) was obtained from poultry manure application which was similar with recommended rate of fertilizer. The study suggested that application of poultry was found more beneficial and significantly improved growth and yield of radish. Int. J. Appl. Sci. Biotechnol. Vol 7(1): 39-42

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.

Radiation Use

Canola tolerant to the triazine group of herbicides is grown widely in Australian broad-acre cropping systems. Triazine-tolerant (TT) cultivars are known to have a yield and oil content penalty compared with non-TT cultivars. This study was designed to elucidate the crop physiological basis for the yield differences between the two types. Two commercial cultivars, near-isogenic for the TT trait, were compared in a detailed growth analysis in the field, and 22 crops were compared for phenology and crop attributes at maturity. In the growth analysis study, the TT trait was found to lower radiation use efficiency, which carried through to less biomass at maturity. There were minimal effects on leaf area development and harvest index, and no effect on canopy radiation extinction. Across the 22 crops, where yield varied from 240 to 3400 kg/ha in the non-TT cultivar, yield was on average 26% less in the TT cultivar due to less biomass produced, as there was no significant effect on harvest index. The difference in oil content (2-5%) was greater in low oil content environments. Flowering was delayed by 2-10 days with a greater delay being in later flowering environments. Quantification of the physiological attributes of TT canola allows the assessment of the productivity of different cultivar types across environments.
