Abstract
The present investigation entitled “Agronomic evaluation of Linseed (Linum usitatissimum L.) in Chickpea + Linseed (4 : 2) intercropping system” was carried out during winter (Rabi) season of 2009–10 at the Agricultural Research Farm, Institute of Agricultural Sciences, Banaras Hindu University, Varanasi, to find out the suitable variety of Linseed in Chickpea + Linseed (4: 2) intercropping system for higher productivity and profitability for this region (Varanasi, U. P.). The field trial was laid out in Randomized Block Design having nine treatments comprising of intercropping of Chickpea + Linseed, sole Chickpea and sole Linseed crop of each variety. Each treatment was replicated three times. The allocation of treatments to the individual plots in each replication was done randomly. Maximum plant population, plant height, number of branches per plant, fresh and dry weight of shoot of Chickpea and Linseed was recorded in the intercropping of Chickpea + Linseed cv. Shekhar (T2) followed by cv. Shubhra (T4), while the minimum was with cv. Padmini (T1). In sole Linseed crop also, cv. Shekhar (T7) recorded maximum on all parameters followed by cv. Shubhra (T9) and the minimum remained with cv. Padmini (T6). Linseed cv. Shekhar emerged as superior over all other varieties in relation to vegetative growth of Linseed, both in case of intercropping with Chickpea as well as sole crop. Chickpea and Linseed recorded maximum number of pods / capsules per plant, number of grains per pod / seeds per capsule, test weight, seed index, grain / seed, straw and fibre yield and harvest index in the intercropping of Chickpea + Linseed cv. Shekhar (T2) followed by cv. Shubhra (T4), while the minimum was with cv. Padmini (T1). In sole Linseed crop also, cv. Shekhar (T7) recorded maximum on all parameters followed by cv. Shubhra (T9) and the minimum remained with cv. Padmini (T6). In relation to yield attributes and yield of Chickpea + Linseed, as well as Linseed alone, cv. Shekhar emerged as significantly superior over all other varieties of Linseed. Land equivalent ratio was found maximum in T2 (Chickpea + Linseed cv. Shekhar) followed by T4 (Chickpea + Linseed cv. Shubhra) and the minimum was with T1 (Chickpea + Linseed cv. Padmini). In the intercropping system of Chickpea + Linseed, combination of Linseed cv. Shekhar and Chickpea recorded maximum grain, straw and fibre yield of Chickpea; seed, straw and fibre yield of Linseed; gross return, net return and benefit cost ratio; followed by cv. Shubhra and the minimum was with cv. Padmini. In sole Linseed crops, although seed, straw and fibre yield was slightly more as compared to intercropping with Chickpea, the gross return, net return and benefit cost ratio was only marginal. Linseed cv. Shekhar intercropped with Chickpea was found best in relation to growth, yield and yield attributes, land equivalent ratio and economic feasibility for cultivation of Linseed in intercropping system under the agro-climatic conditions of this region (Varanasi, Uttar Pradesh). In view of the findings and results presented above, it may be concluded that Linseed cv. Shekhar in Chickpea + Linseed (4: 2) intercropping system was most suitable for higher growth, productivity and profitability under the environmental conditions of Varanasi region. However, since this is based on one-year experiment, further trials may be needed to substantiate the results.
