Description ABSTRACT
The present investigation entitled “Seed priming and integrated nutrient management studies in bell pepper (Capsicum annuum L.) was carried out in the laboratory of Department of vegetable science and experimental farm of Horticultural Research & Training Station and KVK, Kandaghat of Dr YS Parmar University of Horticulture and Forestry, Nauni, Solan HP during 2013-14 and 2014-15. There were two experiments one on priming in the laboratory and another on integrated nutrient management in the field. The seeds of bell pepper cv. Solan Bharpur were primed with 23 treatments comprising of osmopriming halopriming, hormonal priming, hydroprimg, priming with cow urine and control (untreated). The laboratory studies were carried out in a CRD with four replications for germination and vigour test conducted at 20 and 25oC using germinator and paper towel as well as in sand under ambient conditions before storing them for one week, 3, 6, 9 and 12 months. The seeds were primed at sub optimal temperature (20oC) and were tested immediately after priming as well as after every storage periods. It was found that seed priming with GA3100ppm for 48 h exhibited best results in terms of characters like speed of germination, germination, seedling dry weight ,seedling vigour index-I and seedling vigour index-II whereas seedling length was recorded maximum when the seeds were seed treated with KH2PO4. The storage life of primed seeds was maximum after one week, however, it got declined gradually when the period of storage was increased.
In the field studies, the primed and unprimed seeds were sown during February 2014 and 2015 in a factorial RBD with three replications having plot size of 2.7 x 2.4 m and with a spacing of 60 x 45 cm. The best priming treatment was combined with seven INM treatments which were compared with seven other INM treatments without priming. It was found that application of 75% N + remaining 25% N through FYM + PM + full quantity FYM, P and K + PGPR (T4) produced minimum values for days to first flowering, days to marketable maturity, soil pH, incidence of fruit rot and severity of leaf blight, whereas, the same treatment i.e. T4 produced maximum values for characters like harvest duration, yield per plot and per hectare, organic carbon in soil, available phosphorous and copper in soil as well as uptake of potassium, zinc, iron and manganese by the plants. In addition to this, maximum gross income, net returns and net B: C ratio was also worked out in T4. On the other hand, T6 produced maximum values for characters like average fruit weight, number of laterals/plant, plant height, available nitrogen, potassium, zinc, iron and manganese in soil along with uptake of nitrogen, phosphorous and copper by the plants. Maximum ascorbic acid and longer shelf life were obtained in T5, whereas maximum TSS was recorded in T3. Therefore, application of 75% N + remaining 25% N through FYM + PM + full quantity FYM, P and K + PGPR (T4) may be recommended to the growers after on farm testing in multilocation trials for better germination and storage of seed in addition to high quality yield.
