Planting System

Rice is the main commodity crops in the province of Gorontalo, in addition to maize and pulses. One alternative technology to increase productivity is through application of Legowo cropping system that is engineered way of planting the tiles so that there is a spacious room extends to one direction between two rows of rice plants, while the other way seemed more tightly. In rice cultivation with system of transplanting, planting distance is one factor of production that is very important because it determines the productivity achieved. This research is expected to be a reference for farmers, especially in the province of Gorontalo to carry rice cultivation so as to increase the production of rice plants. The design of the study is a Randomized Complete Block Design by comparing between systems that are often used by farmers, namely row planting system tiles (S0), the system of row planting Legowo (2: 1) (S1), system of row planting Legowo (4: 1 ) (S2), planting system SRI (S3). The parameters of observations made were plant height, number of tillers, production (kg/plot), and observations of soil samplesman. The results showed treatment plant system of tiles provide number of tiller and height of plants that are best compared with other treatments. The best results for a number of productive tillers, the average production of grain/plot, grain weight of 1000 grain was in the treatment plant system Legowo row 2: 1.

Rice Intensification

Field experiment was conducted at Rice Research Station, Bankura during kharif season 2009 and 2010 to study the yield potentiality and spatial requirement of rice varieties in system of rice intensification (SRI) under red and laterite zone of West Bengal. The experiment was laid out in a randomized complete block design (RCBD) in a three replications with two rice varieties (Swarna and Lalat). Performances of swarna and lalat varieties in SRI as compared to conventional method of rice cultivation (CMRC) were investigated. Swarna (MTU 7029) has yielded maximum grain yield (6.07, 5.66 and 5.86 t ha-1 during 2009, 2010 and in pooled, respectively) from the treatment T7 (25 × 25 cm spacing) under SRI. Lowest grain yield (3.55, 3.23 and 3.38 t ha-1 during 2009, 2010 and in pooled, respectively) was recorded from treatment T9 (Lalat at 20 × 15 cm spacing) under CMRC. SRI technology has potential in increasing more grain yield, it saves seed requirement and irrigation water and chemical fertilizer considering than conventional method of cultivation. Rice cultivation is more sustainable and profitable for the farmers in SRI under the red and laterite zone of West Bengal.

Rice (Oryza sativa L) is the most important staple food crop in Nepal, but current yields are low and total production varies, mostly due to drought. To evaluate high yielding and drought tolerant rice genotypes in typical rainfed lowland conditions, a participatory varietal selection trials was conducted with farmers in farmer’s field at Sundarbazar, Lamjung, Nepal during the wet season 2009 and 2010. Trials were laid out in a Randomized Complete Block Design with six replications. Results obtained from two years’ experiment indicated that the genotypes IR-74371-54-1 and IR74371-70-1 matured at the same duration as the local check Radha-4 (120-123 days growth duration). Both genotypes had a high average chlorophyll content (SPAD reading of 15.9-16.1), were medium tall (110-112 cm), non-lodging, had a high number of filled grains and little sterility, and a high grain yield (mean yield 5.0 and 4.8 t ha-1, respectively). They also had the highest root length (22.4-26.2 cm) and root weight (9.5-10 g hill-1) which could tolerate more drought than the other genotypes tested. The maximum cost/benefit ratio was found in IR-74371-54-1 (1:1.72) followed by IR-74371-70-1 (1:1.66) and IR-74371-46-1-1 (1:1.65). All three lines were highly preferred by farmers in preference rankings during field visits and were released in Nepal in 2011 as Sookhadhan-2, Sookhadhan-3 and Sookhadhan-1 varieties, respectively. They fit easily into the existing cropping system in rainfed lowlands, are economically viable and safe to cultivate for the farmers in the mid hills of Nepal.Journal of the Institute of Agriculture and Animal Science.Vol. 33-34, 2015, page: 195-206

Fate Of Nitrogen

Because of their potential for N2 biological fixation, legumes are an alternative source of nitrogen to crops, and can even replace or supplement mineral fertilization. A greenhouse experiment was carried out to evaluate temporal patterns of velvet bean (Mucuna aterrima) green manure release of nitrogen to rice plants, and to study the fate of nitrogen from velvet bean in rice cultivation. The isotopic dilution methodology was used. Treatments consisted of a control and 10 incubation periods of soil fertilized with 15N-labeled velvet bean (0, 20, 40, 60, 90, 120, 150, 180, 210, and 240 days). The plant material was previously chopped, sifted (10 mm mesh sieve) and oven-dried (65ºC). Incubation of the plant material (2.2 g kg-1 soil) was initiated by the longest period, in order to synchronize the planting of the test crop, rice (Oryza sativa), at time zero for all treatments. Green manure incorporation promoted increases in rice dry matter yield and nitrogen uptake. These variables showed maximum values at incubation periods of 38 and 169 days, respectively. Green manure nitrogen utilization by rice plants was highest at an incubation period corresponding to 151 days. More than 60% of the green manure nitrogen remained in the soil after rice cultivation. The highest green manure nitrogen recovery from the soil-plant system occurred at an incubation period equivalent to 77 days.

A field experiment was conducted to study the effect of dates of transplanting under different methods of cultivation on productivity of winter rice (Oryza sativa L.) and their effect on rice-niger (Guizotia abyssinica) relay system at Regional Agricultural Research Station, Shillongani Nagaon, Assam during kharif-rabi seasons in the year 2014-15 and 2015-16. Rice transplanted on 20 June recorded significantly higher yield attributes and grain yield of rice (59.19 q/ha) as compared to the later dates of transplanting, and it was followed by 5 July- transplanted rice. Transplanting on 20 June resulted in higher values in respect of yield attributes, yield of relayed niger, rice equivalent yield (REY) of rice- niger relay system (75.68 q/ha), NPK uptake by rice and niger as well as soil fungal and bacterial population after harvest of rice and niger. System of Rice Intensification (SRI) recorded significantly higher value of yield attributes and grain yield of rice (60.34q/ha) as compared to conventional method. In case of relayed niger, yield attributes, seed yield and REY were found higher under SRI method of rice cultivation. Under SRI method, higher uptake of NPK by rice and niger and higher soil fungal and bacterial populations after harvest of rice and niger were observed as compared to conventional method. However, conventional method of rice cultivation recorded significantly higher values of soil available N, P2O5 and K2O content at the end of two year-crop cycle over that of SRI.
