A field experiment was conducted during rainy (kharif) and winter (rabi) seasons of 2014-15, 2015-16 and 2016-17 at Imphal, Manipur, to study the performance of intercropping chickpea (Cicer arietinum L.) and lentil (Lens culinaris Medik.) with linseed (Linum usitatissimum L.) and Indian mustard [Brassica juncea (L.) czernj. and cosson] under 2 varying preceding kharif lowland rice (Oryza sativa L) crop durations and also to evaluate the system productivity and profitability. Planting of medium duration rice variety enhanced growth and yield of rabi crops resulting in increase in system productivity in terms of rice equivalent yield (REY) and production efficiency (PE) by 5.4 %, and 14.5%, respectively over planting of late duration rice variety. Seed and biological yields of chickpea, lentil, Indian mustard and linseed were higher in sole cropping than in intercropping systems. Indian mustard and linseed were found dominant and aggressive as compared to chickpea and lentil. Chickpea and Indian mustard intercropping under 4:2 ratio proved more remunerative and recorded higher yield advantage than either of chickpea and linseed or lentil and Indian mustard intercropping as judged by REY (9.7 tonnes/ha), crop productivity (39.9 kg/ha/ day) and net return (` 81,168/ha). Land equivalent ratio (LER) of chickpea with Indian mustard (1.10) remained at par with intercropping chickpea with linseed (1.17), however, lentil intercropped with Indian mustard had less than unity LER of 0.87.

Abstract Background Calcareous soils are highly deficient in boron (B) which has become one of the most important deficient micronutrients in Indian soil after zinc (Zn). For various rice-based cropping systems, B-fertilization is essential for increasing crop productivity and the biofortification of the crop, thus suitable soil application protocol for B-fertilization are required for B-deficient soils. Results In a six years-long experiment, different rates of B application viz. 0.5, 1.0, 1.5, and 2.0 kg ha− 1 y− 1 were evaluated to determine the effects of three different modes of B fertilization viz. applied only in the first year, in alternating years, and every year in rice ( Oryza sativa L.) – Indian mustard (Brassica juncea L.) cropping system. It was observed that the application of B at 1.5 kg ha− 1 in every year or 2 kg ha− 1 in alternate years resulted in the highest yield of rice and mustard as well as the system productivity of the rice–mustard cropping system. Application of 2 kg ha− 1 B in the initial year showed the maximum B-uptake by rice, while, application of 1.5–2.0 kg ha− 1 B in every year resulted in the maximum B-uptake by the mustard crop. Conclusion Application of B at 2 kg ha− 1 in alternate years or 1.5 kg ha− 1 in every year was the best B-application protocol under rice–mustard cropping system in B-deficient calcareous soils for ensuring the best system productivity of rice–mustard cropping system and B-availability in soil.

B Uptake

Calcareous soils are highly deficient in boron (B) due to having high levels of free CaCO3 and low organic matter. This has become one of the most important deficient micronutrients in Indian soil after zinc (Zn). For various rice (Oryza sativa L.)-based cropping systems, B fertilization is essential for increasing crop productivity and the biofortification of the crop, thus a suitable soil application protocol for B fertilization is required for B-deficient soils. In a six-year experiment, different rates of B application, namely, 0.5, 1.0, 1.5, and 2.0 kg ha−1 y−1, were evaluated to determine the effects of three different modes of B fertilization, i.e., applied only in the first year, applied in alternating years, and applied every year, in a rice (Oryza sativa L.)–Indian mustard (Brassica juncea L.) cropping system. It was observed that the application of B at 1.5 kg ha−1 every year or 2 kg ha−1 in alternate years resulted in the highest yield of rice and mustard, as well as the maximum system productivity of the rice–mustard cropping system. Application of 2 kg ha−1 of B in the initial year showed the maximum B uptake by rice, while application of 1.5–2.0 kg ha−1 of B every year resulted in the maximum B uptake by the mustard crop. Application of B at 2 kg ha−1 in alternate years or 1.5 kg ha−1 every year was the best B-application protocol in B-deficient calcareous soils for ensuring the highest productivity of the rice–mustard cropping system and B availability in the soil.

The experiment was conducted to find out the effect of plant spacing on the performance of rice variety IR-64 and IR64-Sub1 under conventional and Submerged condition at the National Rice Research Institute (NRRI), Cuttack, Odisha during the Rabi season of 2018. Different planting densities were maintained using different spacing's. These include (S1) 15 cm × 10 cm, (S2) 15 cm × 20 cm. The experiment was laid out in a randomized complete block design with 3 replications spacing of 15 cm × 10 cm with produced the highest grain yield of 350 gm-2 in submerged condition on IR64-Sub1 rice cultivar, which was significantly higher than the yield with recommended density (15 cm × 10 cm with IR64 Sub1). This yield was increased due to higher number of panicles m-2. This result suggests that higher planting density (15 cm×10 cm) rather than increased number of seedling hill-1 is necessary for getting higher yield of IR-64Sub1 rice cultivar in continuous submerged condition (where V1=IR 64, V2=IR-64 Sub1, S1=15 cm×10 cm, S2=20 cm×15 cm).

The Impact

Rice (Oryza sativa L.) is the second most important crop in the world after wheat and also the most important crop in Nepal. The production of rice is influenced by various biotic and abiotic factors. Temperature is the major constraint for the crop yield. The present experiment was conducted to study the impact of temperature on straw and crop productivity from June to October 2014. The experiment was conducted under temperature control chamber, in which temperature was elevated from the ambient level by 2ºC and 3ºC for the entire crop growth period. Grain and straw yield was measured using electronic weighing machine. Maturity of grain was 10 and 7 days earlier at elevated temperature by 3ºC and 2ºC respectively. Under similar condition of water depth, plant spacing, rice variety and soil nutrient, rise in temperature up to 2ºC is favorable for rice straw yield and crop productivity. Yield loss under elevated temperature by 3ºC is due to floret sterility. Further research on temperature resistance rice variety is necessary.

Rice Genotypes

Salinity is one of the major abiotic stresses, which adversely affects the crop productivity. Thirty rice genotypes of diverse origin including three salt tolerant check varieties, Binadhan-8, Binadhan-10 and Pokkali, were used to evaluate salt tolerance at seedling stage and to determine the genetic diversity using microsatellite markers. Salinity screening was done at the seedling stage using hydroponic system following IRRI standard protocol. Three salinity levels as 6dSm-1, 8dSm-1, and 10dSm-1 were used along with control. Data were recorded on root length, shoot length and dry weight and the genotypes were scored based on modified standard evaluation score (SES) for visual injury. Sixteen SSR markers were used to study the genetic variation within 30 rice genotypes. A total of 65 alleles with an average of 4.06 allele per locus were detected among 30 rice genotypes. The polymorphism information content (PIC) value ranged from 0.24 to 0.86 with an average of 0.51. The unweighted pair group method with arithmetic mean (UPGMA) dendrogram revealed four clusters. Among them cluster I identified 5 salt tolerant genotypes and cluster IV separated one tolerant and one moderately tolerant genotype. Based on SES evaluation and molecular analysis genotypes Balam, THDB, Q-31, Ab.Hai, BR-5, FR13A ware salt tolerant; Moulota, Super hybrid, Y-1281, Binadhan-16 were moderate salt tolerant. This information could be useful for selection of suitable genotypes for developing salt tolerant rice variety through molecular breeding.

The Impact

Shifting cultivation, locally known as jhum, is the predominant agricultural practice for most communities inhabiting the uplands of north-east India. The negative impacts of the practice on forest and biological resources, soil erosion and land degradation have been a serious concern for several decades now to administrators and planners as well as to the academic community. In the current context, the practice has undergone drastic changes and has become increasingly unviable, gradually leading to the marginalization of farmers practising it. Although shifting cultivation in this area has been the focus of intensive studies, particularly in terms of the underlying ecological dynamics, few have attempted to analyse the factors contributing to the marginalization of the practice. This paper examines micro-scale issues that contribute to reducing productivity (and hence marginalization), and which are of immediate concern to the shifting cultivator. The paper focuses on fundamental issues influencing the reduction in fallow cycle lengths, the impact of rural–urban migration on labour requirements for agriculture, the consequences of inadequate employment and cash generation facilities on labour availability and crop productivity, as well as government efforts to promote agricultural productivity in these areas. The main focus of the paper is on the impact of each of these factors and their synergystic effect on the marginalization of shifting cultivation.

The present investigation was conducted to study the growth and yield response of local rice cultivars to application of recommended dose of NPK fertilizers under upland rainfed conditions. It was found that the application of recommended NPK fertilizer dose (60:30:30 kg/ha) resulted in significantly superior expression of rice growth and yield attributes by the different cultivars recording increased grain yields up to 36.51 q/ha and straw yields of 60.96 q/ha. Among the 8 local rice cultivars tested signification variations in plant growth, yield and yield attributes were observed. However, the cultivar ‘Muntse’ was found to be the most adaptable rice variety recording the highest grain yield of 42.94 q/ha followed by ‘Temeseng’, ‘Leikhumo’ and ‘Chongloi Mann’. Application of recommended fertilizer dose (60:30:30 kg/ha) to the cultivar ‘Mumtse’ was found to record the highest gross return/ha (Rs.51,342), net return/ha (Rs. 30,169) as well as BCR (1.42) compared to the rest of the treatments tested.

Crop stresses due to both biotic and abiotic are the major factors affecting crop productivity. The need of the hour is to minimize the yield losses due to these stresses. Early detection can help to reduce the impact of stresses on crop growth and yield. Remote sensing techniques have been shown to be timely, non-destructive and provide spatial estimates for quantifying and monitoring crop stress as compared to direct field techniques. In this study we tested the possibility of detecting impact of abiotic stresses, mainly Nitrogen (N) and elevated CO2 and Temperature on growth and yield of rice crops based on the spectral reflectance data in the red edge position (REP). Spectral reflectances of crop canopyi from 350 to 2500 nm acquired using SVC spectroradiometer under clear sky condition between 11:00 and 13:00 IST. The results thus obtained indicate that REP is a good indicator of crop stress detection as healthy crops always are at longer wavelength as compared to crop under stress. The research work done also elucidates that REP can lead to the development of real-time management tool for crop stress detection, thereby reducing the yield losses due these stresses.
