Abstract:
Pulses are an important source of high quality protein complementing cereal proteins for pre-dominantly substantial vegetarian population of the country. Pigeonpea (Cajanus cajan (L.) Millsp.) is the second most important pulse crop of India after chickpea and is grown for it’s grain as dhal and green seed as a vegetable. A field experiment was conducted at College of Agriculture, Vishweshwaraiah Canal Farm, Mandya during kharif 2017 to study the effect of foliar application of calcium nitrate, boron and humic acid on growth and yield of transplanted pigeonpea. The design followed is randomized complete block design with three replications. Higher nitrogen content in grain and stover (3.42% and 1.28%, respectively), phosphorous content in grain and stover (0.49% and 0.34%, respectively) and potassium content in grain and stover (0.9% and 1.1%) was recorded for the treatment with foliar spray of humic acid 6 ml L-1 at flowering initiation and 15 days after flowering initiation along with RDF and FYM (T13), protein per cent in grain also followed the similar trend. Higher concentration of calcium in grain and stover (0.37% and 1.2%) was recorded in treatment with foliar spray of 2.0% Ca(NO3)2 at flowering initiation and 15 days after flowering initiation along with RDF and FYM (T9). Higher boron content in grain and stover (23.87 mg kg-1 and 32.27 mg kg-1) was recorded in treatment with foliar spray of 0.50% borax at and 15 days after flowering initiation along with RDF and FYM (T11). Foliar spray of humic acid 6 ml L-1 at flowering initiation and 15 days after flowering initiation along with RDF and FYM (T13) recorded the higher uptake of nitrogen, phosphorous and potassium by grain (71.52, 10.27 and 18.84 kg ha-1 respectively) and stover (95.08, 25.26 and 81.46 kg ha-1 respectively). Higher uptake of boron by grain and stover (46.69 g ha-1 and 230.81 g ha-1 respectively) was recorded in foliar spray of 0.50% borax at flowering initiation and 15 days after flowering initiation along with RDF and FYM.
