Background: Blackgram is generally considered as a shade sensitive crop. Nevertheless, it fits well in intercropping, crop rotation and crop mixture in coconut gardens thus forming an integral part of cropping systems of the tropics. To encourage and extend blackgram cultivation in coconut gardens, suitable varieties tolerant to shade, need to be identified. The current study aims to screen shade tolerant blackgram varieties with respect to morpho-physiological characters and yield. Methods: Field experiment was conducted during Rabi 2019 at College of Agriculture, Vellayani, Kerala, India. Uniformly spaced coconut palms of age above 40 years were selected having a light intensity of 40-46.5 Klux. Twelve promising blackgram varieties along with three cultures were evaluated under low light intensity in coconut garden. Morpho-physiological attributes and yields were recorded and analysed statistically. Result: Superior growth attributes and physiological parameters like stomatal frequency, chlorophyll content, photosynthetic rate and transpiration rate were recorded in varieties namely, DBGV 5, Sumanjana and VBN 5. These varieties were found tolerant to low light intensity with DBGV 5 recording significantly higher yield (1183.33 kg ha-1) followed by VBN 5 (916.67 kg ha-1) and Sumanjana (906.67 kg ha-1) and could be recommended as suitable for intercropping in coconut garden.

Present experiment was conducted during 2011-12 and 2012-13 at the research farm of Jawaharlal Nehru Krishi Vishwa Vidyalaya (JNKVV), Jablapur, Madhya Pradesh to study the performance of rice under various rice-based cropping systems. Total 12 rice-based cropping systems viz., rice followed by wheat, chickpea, onion-green gram, berseem, potato-sesame, gobhi sarson-black gram, vegetable pea-sesame, potato- ground nut, gobhi sarson- sorghum, gobhi sarson- okra, French bean and marigold-sesame were studied during the study period. The performance of rice was assessed by monitoring growth attributes (plant height, effective tillers, panicle length, weight of panicle, sterility percentage etc.), yield attributes (grains per panicle, test weight etc.) and grain yield. The results revealed that, among the various cropping system studied the performance of rice crop was found statistically superior under rice-wheat and rice-chickpea cropping sequence. The poor performance of rice crop was observed under rice-berseem followed by rice-marigold-sesame cropping system.

Extract Information

The present study was carried out in three districts viz; Rewari, Sirsa and Hisar of Haryana state. A survey of 60 sampled farms was conducted to extract information pertaining to various expenses incurred in cultivation of castor and output attained as well as to ascertain the perception of farmers for various problems encountered in production and marketing of castor seed. The descriptive analysis was employed to draw valid inferences from the study. The results revealed that net profit accrued from cultivation of castor seed was ₹ 46331 ha -1 in the study area. The value of B: C ratio of castor cultivation was more than one and also higher as compared to prevalent cropping systems indicated that cultivation of castor seed is economical viable entity. However, production constraints like retention of F2 seed in the field over year, grain scattering, shortage of irrigation water, frost effect on crop yield and marketing constraints like absence of MSP, higher transportation cost sale of castor seed in distant markets, frequent fluctuation in market price, non-availability of processing units were observed.

Recognition of high yielding and nitrogen (N) fixing groundnut genotypes and desegregating them in the cereal-based cropping systems common in savannah regions will enhance food security and reduce the need for high N fertilizers hence, minimize the high cost and associated environmental consequences. Field trials were conducted during the 2015 growing season at the Research Farms of Bayero University Kano (BUK) and Institute for Agricultural Research (IAR), Ahmadu Bello University, Samaru-Zaria to assess the yield potential and Biolog- ical N fixation in 15 groundnut genotypes (ICG 4729, ICGV-IS 07823, ICGV-IS 07893, ICGV-IS 07908, ICGV- SM 07539, ICGV- SM 07599, ICGV-IS 09926, ICGV-IS 09932, ICGV-IS 09992, ICGV-IS 09994, SAMNUT-21, SAMNUT-22, SAMNUT-25, KAMPALA and KWANKWAS). The groundnut genotypes and reference Maize crop (SAMMAZ 29) were planted in a randomized complete block design in three replications. N difference method was used to estimate the amount of N fixed. The parameters determined were the number of nodules, nod- ule dry weight, shoot and root dry weights, pod, and haulm yield as well as N fixation. The nodule dry weight, BNF, haulm, and pod yield were statistically significant (P<0.01) concerning genotype and location. Similarly, their interac- tion effect was also highly significant. ICGV-IS 09926 recorded the highest nod- ule dry weight of 2.07mg /plant across the locations while ICGV-IS 09932 had the highest BNF value of 140.27Kg/ha. Additionally, KAMPALA had the high- est haulm yield, while ICGV-IS 07893 had the highest pod yield across the loca- tions with a significant interaction effect. The result shows that ICGV-IS 07893 and ICGV-IS 09932, as well as ICGV-IS 09994 and SAMNUT – 22, were the best genotypes concerning BNF, haulm and pod yield in the Northern Guinea and Sudan Savannahs of Nigeria respectively with the potential for a corresponding beneficial effect.
